Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value 
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.

Merge pull request #1679 from thasti/delay-parsing 
Fix crash on wire declaration with delay
 2020-02-13 12:01:27 +01:00
whitequark c34d7b13f4 ast: avoid intermediate wires/assigns when lowering to AST_MEMINIT. 
Before this commit, every initial assignment to a memory generated
two wires and four assigns in a process. For unknown reasons (I did
not investigate), large amounts of assigns cause quadratic slowdown
later in the AST frontend, in processAst/removeSignalFromCaseTree.
As a consequence, common and reasonable Verilog code, such as:
  reg [`WIDTH:0] mem [0:`DEPTH];
  integer i; initial for (i = 0; i <= `DEPTH; i++) mem[i] = 0;
took extremely long time to be processed; around 80 s for a 8-wide,
8192-deep memory.

After this commit, initial assignments where address and/or data are
constant (after `generate`) do not incur the cost of intermediate
wires; expressions like `mem[i+1]=i^(i<<1)` are considered constant.
This results in speedups of orders of magnitude for common memory
sizes; it now takes merely 0.4 s to process a 8-wide, 8192-deep
memory, and only 5.8 s to process a 8-wide, 131072-deep one.

As a bonus, this change also results in nontrivial speedups later
in the synthesis pipeline, since pass sequencing issues meant that
all of these intermediate wires were subject to transformations such
as width reduction, even though they existed solely to be constant
folded away in `memory_collect`.

Jeff Wang 98c6bd7630 fix bug introduced by not taking all of PeterCrozier's changes in 16ea4ea6 
The if(str == node->str) is in fact necessary (otherwise causes generate
for in Multiplier_2D in tests/simple/multiplier.v to fail with error
message "Right hand side of 3rd expression of generate for-loop is not
constant!"). Note: in PeterCrozier's implementation, the break only
breaks out of the switch-case, not the outer for loop.

Jeff Wang 16ea4ea61a partial rebase of PeterCrozier's enum work onto current master 
I tried to keep only the enum-related changes, and minimize the diff. (The
original commit also had a lot of work done to get typedefs working, but yosys
has diverged quite a bit since the 2018-03-09 commit, with a new typedef
implementation.) I did not include the import related changes either.

Original commit:
"Initial implementation of enum, typedef, import.  Still a WIP."

Merge pull request #1406 from whitequark/connect_rpc 
rpc: new frontend
 2019-09-30 17:38:20 +00:00
whitequark 99a7f39084 rpc: new frontend. 
A new pass, connect_rpc, allows any HDL frontend that can read/write
JSON from/to stdin/stdout or an unix socket or a named pipe to
participate in elaboration as a first class citizen, such that any
other HDL supported by Yosys directly or indirectly can transparently
instantiate modules handled by this frontend.

Recognizing that many HDL frontends emit Verilog, it allows the RPC
frontend to direct Yosys to process the result of instantiation via
any built-in Yosys frontend. The resulting RTLIL is then hygienically
integrated into the overall design.
