* verific: Fix enum_values support and signed attribute valuesJannis Harder2023-03-151-34/+33
| | | | | | This uses the same constant parsing for enum_values and for attributes and extends it to handle signed values as those are used for enums that implicitly use the int type.

|\ | | | | verific: Improve logic generated for SVA value change expressions
| * verific: Improve logic generated for SVA value change expressionsJannis Harder2022-05-091-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | verific: Fix conditions of SVAs with explicit clocks within proceduresJannis Harder2022-05-033-5/+16
|/ | | | | | | | | 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.
