 ## Tool Installation
 
-There are different ways to install and develop OpenROAD and ORFS, which is the best fit depends use-case, experience and personal taste.
+There are multiple ways to install and develop OpenROAD and ORFS. However, the best option depends on your use case, experience level, and personal preference.
+
+
+> **Recommendation for new users:**  
+> If you are new to OpenROAD-flow-scripts, Docker can be a reliable way to get started since it avoids most dependency and environment issues.  
+>  
+> On supported platforms, using the pre-built binaries can be an even simpler option as it avoids building from source.  
+>  
+> Alternatively, the Bazel-based flow also avoids manual dependency installation (aside from installing Bazelisk itself), similar to how Docker requires installing Docker.
+
+
 
 ### Use Bazel, avoid installing anything at all and adapt the flow to your needs in your own repository

Set to 1 to change the behavior to generate artifacts upon failure to e.g. do a global route. The exit code will still be non-zero on all other failures that aren't covered by the "useful to inspect the artifacts on failure" use-case. Example: just like detailed routing, a global route that fails with congestion, is not a build failure(as in exit code non-zero), it is a successful(as in zero exit code) global route that produce reports detailing the problem. Detailed route will not proceed, if there is global routing congestion This allows build systems, such as bazel, to create artifacts for global and detailed route, even if the operation had problems, without having know about the semantics between global and detailed route. Considering that global and detailed route can run for a long time and use a lot of memory, this allows inspecting results on a laptop for a build that ran on a server.| 0|

Yosys will generally infer memories from behavioral Verilog code, whether the memories are in standalone modules or instantiated within some larger module. fakeram and empty Verilog memories(blackboxes) of memories will not be inferred memories by Yosys and are therefore not affected by this variable. This is useful and convenient to separate the concern of instantiating and placing memories from investigating other issues with a design, though it comes at the expense of the increased accuracy that using realistic fakemem would provide. Memories with a single 1 row will of course have unrealistically good timing and area characteristics, but timing will still correctly terminate in a register. Large port memories, typically register files, will still have the retain a lot of the port logic that can be useful to investigate issues. This can be especially useful during development of designs where the behavioral model comes first and suitable memories are matched up when the design RTL is stable. A typical use case would be Chisel which will generate a behavioral model for a memories with the required clocks, ports, etc. in addition to a computer readable file with the specification of the memories that is used to [automatically](https://chipyard.readthedocs.io/en/stable/Tools/Barstools.html/) match up suitable memory macros later in the flow. During an architectural screening study, a large range of memory configurations can be investigated quickly with this option, without getting bogged down in the concern of how to realize the memories in silicon for emphemral RTL configurations that exist only long enough to run through the ORFS flow to create a table of some characteristics of a design configuration.| 0|

The main use case is to quickly identify if performance can be improved by manually retiming the input RTL. Retiming will treat module ports like register endpoints/startpoints. The objective function of retiming isn't informed by SDC, even the clock period is ignored. As such, retiming will optimize for best delay at potentially high register number cost.

+# Tips on building large design
+
+Large designs can quickly result in unmanageable turnaround times for tweaking and fixing if the design contains behavioral memory models, because these memories are by default translated to flip flops.
+
+ORFS has a `SYNTH_MEMORY_MAX_BITS` that limits the size of inferred memories that are translated to flip flops to avoid doomed synthesis runs that will "running forever", instead ORFS will error out early, normally within minutes.
+
+Behavioral models of memories are used in simulation and FPGA tools oftentimes automatically combine hard memory macros with some extra logic to match the behavioral model. OpenROAD does not do such automatic memory inference and matching against real memories or fakemem.
+
+## Doing a screening build
+
+Before deciding how to set up a flow, it is useful to do a "screening build". All we're intersted in here is to know which modules we have and their relative sizes. This can help us identify memories that have not been successfully inferred by Yosys, which will manifest itself as very long synthesis times and appear in the OpenROAD hierarchical view with a large number of instances.
+
+The [minimal build configuration](flow/designs/asap7/minimal/README.md)
+ can be useful to do a screening build.
+
+Options useful for a screening build are, check out [config.mk](flow/designs/asap7/minimal/config.mk):
+
+- `SYNTH_HIERARCHICAL=1` and `SYNTH_MINIMUM_KEEP_SIZE=0`, to see all modules in the hierarchical OpenROAD view
+- `SYNTH_MEMORY_MAX_BITS=1024`, set a low threshold initially to get an error with list of memories in the system that will need to be dealt with in some way
+- `SYNTH_MOCK_LARGE_MEMORIES=1` enabled after first seeing the error report with memories. This sets the number of rows in memories larger than `SYNTH_MEMORY_MAX_BITS` to 1, so that synthesis will complete.
+
+## Next steps on memories
+
+- If you're taping out, write some wrapper Verilog for real memories.
+- fakemem can be a good option if available for your PDK. fakemem also needs manually written Verilog wrappers, just like real memories.
+- For architectural exploration, `SYNTH_MOCK_LARGE_MEMORIES=1` could give you adequate timing accuracy and is convenient.

+# Mocking vs fake memories
+
+Configuring fake memories for this design would speed up the ORFS flow and increase accuracy of results, but some effort is required. Two methods for learning something about a design without setting up SRAM are explained here.
+
+## Synthesis with large flip flop memories
+
+By default `SYNTH_MEMORY_MAX_BITS=42000` since no fake memories have been configured for this example design. This is simple, but results in slow builds and unrealistically large amount of flip flops and singificantly slower timing than fakeram or real RAMs.
+
+![RAMs as flops histogram](histogram-sram-as-flops.png)
+
+## Results with `SYNTH_MOCK_LARGE_MEMORIES=1`
+
+To ensure a quick synthesis run and to better understand the design without being slowed down by large memory blocks, we set a `SYNTH_MEMORY_MAX_BITS=1024`. This helps us bypass potential memory-related issues and focus on other ORFS flow issues of the design.
+
+During synthesis, certain modules are reported in error messages when `SYNTH_MEMORY_MAX_BITS=1024` and `SYNTH_MOCK_LARGE_MEMORIES=0`. By explicitly listing these modules in `SYNTH_KEEP_MODULES`, we avoid further optimizations outside of the mocked memories that could obscure the behavior of the rest of the design.
+
+The goal of these settings is to enable a rapid exploration of the flow, providing insights into the design while minimizing complications from large memory structures.
+
+![Mocked memory histogram](histogram-mock-memory.png)
+
+## Other ways to speed up synthesis
+
+There is a small advantage in synthesis time for `SYNTH_MOCK_LARGE_MEMORIES=1`, it shaves off ca. 1 minute on a 3 minute build on a test on a laptop. However, larger designs can have synthesis run into hours if memories are not managed with a bit of care.
+
+For synthesis, yosys-abc actually takes most of the time and SRAMs don't generally change in a design, even if other RTL development continues. It is possible to keep the synthesized netlist for SRAMs list them in `SYNTH_BLACKBOXES` and simply concatenate the already built netlists onto the `1_synth.v` files before continuing the flow.
+
+If large modules that change rarely are kept in a large design and only a small part of the design changes during RTL development, then it is possible to set up a build flow that completes in minutes instead of hours.
+
+## A/B run times
+
+The difference in run-times for mocking and simply instantiating larger flip flop based RAMs is not large on this design, but on designs with bigger SRAMs, the difference can be substantial.

+## Histogram of mocked memories
+
+It can be useful to look at the Endpoint Slack Histogram of mocked memories to examine if some of the paths are overly optimistic with a single row mocked memory or if the paths through the memory has problems even with a single row memory:
+
+Create a path group for the memories in question:
+
+    group_path -through *decode1_0* -name mocked
+
+Now that path group is in the dropdown in the Endpoint Slack Histogram:
+
+![Mocked memory Endpoint Slack Histogram](mocked-histogram.png)
+
+## Conclusion
+
+Above there's no visible difference in the Endpoint Slack histogram for the two approaches. In other words, the design doesn't appear to be terribly sensitive to how RAMs are mocked, other factors dominate and merit further investigation.
+
+ORFS is built on `make`, which shines for simple, fast flows. For larger, complicated, designs and with flows that take a long time to run, it is worth looking beyond `make` to [bazel-orfs](https://github.com/The-OpenROAD-Project/bazel-orfs)

     Maximum number of bits for memory synthesis.

+

+SYNTH_MOCK_LARGE_MEMORIES:
+  description: >
+    Reduce Yosys inferred memories larger than SYNTH_MEMORY_MAX_BITS to 1 row.
+
+    Yosys will generally infer memories from behavioral Verilog code, whether
+    the memories are in standalone modules or instantiated within some
+    larger module.
+
+    fakeram and empty Verilog memories(blackboxes) of memories will not
+    be inferred memories by Yosys and are therefore not affected by
+    this variable.
+
+    This is useful and convenient to separate the concern of instantiating
+    and placing memories from investigating other issues with a design,
+    though it comes at the expense of the increased accuracy that using
+    realistic fakemem would provide.
+
+    Memories with a single 1 row will of course have unrealistically good
+    timing and area characteristics, but timing will still correctly terminate
+    in a register.
+
+    Large port memories, typically register files, will still have the
+    retain a lot of the port logic that can be useful to investigate issues.
+
+    This can be especially useful during development of designs where the
+    behavioral model comes first and suitable memories are matched up
+    when the design RTL is stable.
+
+    A typical use case would be Chisel which will generate a behavioral model
+    for a memories with the required clocks, ports, etc. in addition to a
+    computer readable file with the specification of the memories that
+    is used to
+    [automatically](https://chipyard.readthedocs.io/en/stable/Tools/Barstools.html/)
+    match up suitable memory macros later in the flow.
+
+    During an architectural screening study, a large range of memory
+    configurations can be investigated quickly with this option,
+    without getting bogged down in the concern of how to realize the
+    memories in silicon for emphemral RTL configurations that exist
+    only long enough to run through the ORFS flow to create a table
+    of some characteristics of a design configuration.
