Note that peek() is generally requested to implement arbiters without the need for additional state within the block (or when the outside world uses a pop() as a signal that...

I believe the difficulty in implementing non_blocking_send and peek (see https://github.com/google/xls/issues/1383) are both the simulators we have, their event model and how they differ than the eventual hardware implementation. send_non_blocking...

https://bazel.build/install/ide#autocomplete-for-source-code has additional options. Though if this is only for clang-tidy, then something like: https://github.com/erenon/bazel_clang_tidy can be used without needing a compile.json file.

Some of these differences are due to use of libstdc++ in Cmake/GCC and libc++ by Bazel/LLVM. Bazel/LLVM can be switched to use the system libstdc++ for select platforms via MODULE.bazel...

That's the point. The code isn't relying on the sorted property of sets, so an unordered set is no better and can be considered for a performance/memory fragmentation gain. Sorting...

Below is a list from my last run: ``` //src/rsz/test:pin_swap1-tcl_test FAILED in 5 out of 100 in 1.0s //src/rsz/test:repair_tie11_hier-tcl_test FAILED in 2 out of 100 in 0.7s //src/rsz/test:repair_tie12_hier-tcl_test FAILED in...

Below command can be used to run those tests ``` bazelisk test -c opt //src/rsz/test:pin_swap1-tcl_test //src/rsz/test:repair_tie11_hier-tcl_test //src/rsz/test:repair_tie12_hier-tcl_test //src/rsz/test:resize_slack2-tcl_test --cache_test_results=no --runs_per_test=100 ``` Log files for each run can be found under...

2nd potential location is in the ordering of equivalent cell pins which is a set https://github.com/The-OpenROAD-Project/OpenROAD/blob/3daea177dd24cd2225b7dc5a11c0e66fd22634e6/src/rsz/src/SwapPinsMove.hh#L53 https://github.com/The-OpenROAD-Project/OpenROAD/blob/3daea177dd24cd2225b7dc5a11c0e66fd22634e6/src/rsz/src/SwapPinsMove.cc#L361 https://github.com/The-OpenROAD-Project/OpenROAD/blob/3daea177dd24cd2225b7dc5a11c0e66fd22634e6/src/rsz/src/SwapPinsMove.cc#L297

Adding in comment by @cdleary from https://github.com/google/xls/issues/1335 I imagine this can be wired up to e.g. param nodes, reflecting them having delay in their arrival, in the SDC scheduling problem....
