* backends/firrtl: Ensure `modInstance` is validAki Van Ness2023-02-031-0/+6
| | | | | | | This should fix #3648 where when calling `emit_elaborated_extmodules` it checks to see if a module is a black-box, however there was no validation that the cell type was actually known, and it just always assumed that we would get a valid instance, causing a segfault.

| * smt2: Fix operation width computation for boolean producing cellsJannis Harder2023-02-011-1/+4
| | | | | | | | | | | | | | | | | | | | The output width for the boolean value should not influence the operation width. The previous incorrect width extension would still produce correct results, but could produce invalid smt2 output for reduction operators when the output width was larger than the width of the vector to which the reduction was applied. This fixes #3654

| * Add json.{h,cc} for pretty printing JSONJannis Harder2023-01-113-1/+223
| | | | | | | | | | | | Avoids errors in trailing comma handling, broken indentation and improper escaping that is common when building JSON by manually concatenating strings.
| * sim: New -append option for Yosys witness cosimJannis Harder2023-01-111-5/+14
| | | | | | | | This is needed to support SBY's append option.

| |
| * New kernel/yw.{h,cc} to support reading Yosys witness filesJannis Harder2023-01-113-1/+380
| | | | | | | | | | | | This contains parsing code as well as generic routines to associate the hierarchical signals paths within a Yosys witness file to a loaded RTLIL design, including support for memories.
| * sim: Only check formal cells during gclk simulation updatesJannis Harder2023-01-111-16/+19
| | | | | | | | This is required for compatibility with non-multiclock formal semantics.
| * sim: Internal API to set $initstateJannis Harder2023-01-111-0/+11
| | | | | | | | This is not yet added to any of the simulation drivers.
| * sim: Emit used memory addresses as signals to output tracesJannis Harder2023-01-111-17/+122
| | | | | | | | | | | | | | | | This matches the behavior of smtbmc. This also updates the sim internal memory API to allow masked writes where State::Sa bits (internal don't care - not a valid value for a signal) leave the memory content unchanged.
| * xprop, setundef: Mark xprop decoding bwmuxes, exclude them from setundefJannis Harder2023-01-113-2/+12
| | | | | | | | | | | | | | | | This adds the xprop_decoder attribute to bwmuxes that drive the original unencoded signals. Setundef is changed to ignore the x inputs of these bwmuxes, so that they survive the prep script of SBY's formal flow. This is required to make simulation (via sim) using the prep model show the decoded x signals instead of 0/1 values made up by the solver.
| * smt2: Treat bweqx as xnorJannis Harder2023-01-111-0/+1
| | | | | | | | Without x-bits they are equivalent
| * smt2: Directly implement bwmux instead of using bwmuxmapJannis Harder2023-01-111-2/+4
