Merge pull request #2426 from whitequark/cxxrtl-auto-top 
cxxrtl: run `hierarchy -auto-top` if no top module is present
 2020-11-02 20:58:10 +00:00
whitequark 65083e9520 cxxrtl: run `hierarchy -auto-top` if no top module is present. 
In most cases, a CXXRTL simulation would use a top module, either
because this module serves as an entry point to the CXXRTL C API,
or because the outputs of a top module are unbuffered, improving
performance. Taking this into account, the CXXRTL backend now runs
`hierarchy -auto-top` if there is no top module. For the few cases
where this behavior is unwanted, it now accepts a `-nohierarchy`
option.

Fixes #2373.

Update nexus arch tests to new harness 2020-10-29 14:42:07 +01:00
Ethan Mahintorabi 5c36e7757c This patch adds support for defining the ABC location at runtime instead of at compile time. This is helpful in build systems like bazel which do not have stable locations for binaries or directories during the compilation phase. 
This change should be backwards compatible with the existing behavior.

Marcelina Kościelnicka d3b6b7fe98 xilinx: Fix attributes_test.ys 
This test pretty much passes by accident — the `prep` command runs
memory_collect without memory_dff first, which prevents merging read
register into the memory, and thus blocks block RAM inference for a
reason completely unrelated to the attribute.

The attribute setting didn't actually work because it was set on the
containing module instead of the actual memory.

Marcelina Kościelnicka eb76d35e80 memory_dff: Fix needlessly duplicating enable bits. 
When the register being merged into the EN signal happens to be a $sdff,
the current code creates a new $mux for every bit, even if they happen
to be identical (as is usually the case), preventing proper grouping
further down the flow.  Fix this by adding a simple cache.

Fixes #2409.

Marcelina Kościelnicka 7670a89e1f opt_clean: Better memory handling. 
Previously, `$memwr` and `$meminit` cells were always preserved (along
with the memory itself).  With this change, they are instead part of the
main cell mark-and-sweep pass: a memory (and its `$meminit` and `$memwr`
cells) is only preserved iff any associated `$memrd` cell needs to be
preserved.
