* sf2/cells_sim.v: add IOSTD parameter to I/O cellsTristan Gingold2022-08-311-0/+11
| | | | | This parameter is set by LiberoSoc IPs, so it is needed to avoid errors when using those IPs.
* synth_sf2: add -discard-ffinit option to discard ff initial valueTristan Gingold2022-08-311-1/+11
| | | | | | sf2 ff have no initial values, but some IP cores use initial values. In order to use those cores on sf2, it is required to discard the initial value (to be carefully used).
* Fitting help messages to 80 character widthKrystalDelusion2022-08-241-2/+2
| | | | | | | | | 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.

* Get rid of dffsr2dff.Marcelina Kościelnicka2020-04-151-1/+0
| | | | | | This pass is a proper subset of opt_rmdff, which is called by opt, which is called by every synth flow in the coarse part. Thus, it never actually does anything and can be safely removed.
