KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

Jannis Harder 4bfaaea0d5 verilog: fix size and signedness of array querying functions 
genrtlil.cc and simplify.cc had inconsistent and slightly broken
handling of signedness for array querying functions. These functions are
defined to return a signed result. Simplify always produced an unsigned
and genrtlil always a signed 32-bit result ignoring the context.

Includes tests for the the relvant edge cases for context dependent
conversions.

Merge pull request #3305 from jix/sva_value_change_logic 
verific: Improve logic generated for SVA value change expressions
 2022-05-09 16:40:34 +02:00
Jannis Harder a855d62b42 verific: Improve logic generated for SVA value change expressions 
The previously generated logic assumed an unconstrained past value in
the initial state and did not handle 'x values. While the current formal
verification flow uses 2-valued logic, SVA value change expressions
require a past value of 'x during the initial state to behave in the
expected way (i.e. to consider both an initial 0 and an initial 1 as
$changed and an initial 1 as $rose and an initial 0 as $fell).

This patch now generates logic that at the same time

	a) provides the expected behavior in a 2-valued logic setting, not
	   depending on any dont-care optimizations, and

	b) properly handles 'x values in yosys simulation

Jannis Harder 96f64f4788 verific: Fix conditions of SVAs with explicit clocks within procedures 
For SVAs that have an explicit clock and are contained in a procedure
which conditionally executes the assertion, verific expresses this using
a mux with one input connected to constant 1 and the other output
connected to an SVA_AT. The existing code only handled the case where
the first input is connected to 1. This patch also handles the other
case.
