Jannis Harder a2f9ebe43a memory_map: Add -formal option 
This maps memories for a global clock based formal verification flow.
This implies -keepdc, uses $ff cells for ROMs and sets hdlname
attributes.

Jannis Harder 0cdb14df41 setundef: Do not add anyseq / anyconst to unused memory port clocks 
Instead set those unused clocks to zero.

Jannis Harder 428ad5b9fd wreduce: Keep more x-bits with -keepdc 2022-08-16 13:37:30 +02:00
Jannis Harder 95db5a9d38 formalff: New -setundef option 
Find FFs with undefined initialization values for which changing the
initialization does not change the observable behavior and initialize
them. For -ff2anyinit, this reduces the number of generated $anyinit
cells that drive wires with private names.

Jannis Harder a5e1d3b997 formalff: Set new replaced_by_gclk attribute on removed dff's clks 
This attribute can be used by formal backends to indicate which clocks
were mapped to the global clock. Update the btor and smt2 backend which
already handle clock inputs to understand this attribute.

Jannis Harder c0063288d6 Add the $anyinit cell and the formalff pass 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
use different backends simultaneously.

Merge pull request #3322 from Forty-Bot/default_assignment_first 2022-08-10 09:16:32 +02:00
Sean Anderson 8c05f14b58 Order ports with default assignments first 
Although the current style is allowed by the standard, Icarus verilog
doesn't parse default assignments using an implicit net type:

	techlibs/ice40/cells_sim.v:305: syntax error
	techlibs/ice40/cells_sim.v:1: Errors in port declarations.

Fix this by making sure that ports with default assignments first on
their line.

Fixes: 46d3f03d2 ("Add default assignments to other SB_* simulation models")
