Merge pull request #1551 from whitequark/manual-cell-operands
Clarify semantics of comb cells, in particular shifts
2019-12-05 08:24:24 -08:00
whitequark e97e33d00d kernel: require \B_SIGNED=0 on $shl, $sshl, $shr, $sshr.
Before this commit, these cells would accept any \B_SIGNED and in
case of \B_SIGNED=1, would still treat the \B input as unsigned.

Also fix the Verilog frontend to never emit such constructs.

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.
