Fix sim writeback check for yw_cosim 
Writeback of simulation state into initial state was only working for `run()` and `run_cosim_fst()`.
This change moves the writeback into the `write_output_files()` function so that all simulation modes work with the writeback option.

plugin: shuffled the #ifdef WITH_PYTHON's around to un-tangle the code and pulled out the check for the .py extension so it will complain if you try to load a python extension without python support 2023-05-03 03:35:55 -04:00

7bff8b63b3 rename: Fix renaming cells in -witness mode 
This was renaming cells while iterating over them which would always
cause an assertion failure. Apparently having to rename cells to make
all witness signals public is rarely required, so this slipped through.

ad149cc42a passes: show: Factor out 'join_label_pieces' 
In two places, we are joining label pieces by a '|' separator. We go
about it by putting the separator behind each entry, then removing the
trailing separator in a final fixup pass on the built string. For easier
reading, replace those occurrences by a new factored-out
'join_label_pieces' function.

e3709ce776 passes: show: Fix portbox bit ranges in case of driven signals 
When the 'show' pass generates portboxes to detail the connection of
cell ports to wires, it has special handling of signal chunk
repetitions, but those repetitions are not accounted for in the
displayed bit range in case of cell outputs. Fix that, and so bring it
into consistence with the behavior on cell inputs.

So, taking for example the following Verilog snippet,

  module DRIVER (Q);
     output [7:0] Q;
     assign Q = 8'b10101010;
  endmodule

  module main;
     wire w;
     DRIVER driver(.Q({8{w}}));
  endmodule

make the show pass display '7:0 - 8x 0:0' in the driver-to-w portbox
instead of '7:7 - 8x 0:0' which it displayed formerly.
