Is there is a way to control the $ in net name

[dineshannayya]

I see Yosys tool does Two dimensional register array changed with $ in net name like: u_wb2sdrc.u_cmdfifo.mem**$rdreg[0]$**d[0]

Is there is way to do renaming Rule inside yosys to avoid $ in the netname?

OpenSTA tool is having issue in handling net with $.

The naming rules cannot be changed, but you can change the names after the fact to _<number>_ by running rename -enumerate, avoiding the problem

@mwkmwkmwk This is a public name; so rename -enumerate won't do anything to it.

Is there a plan to fix this net naming with $ issue .. As this $ will be propagated inside the .spef file and Open STA tool is not handing this. When i raised the issue with Open STA tool, they say's "is illegal to have $ in net name"

May I ask which version of yosys are you using? I explicitely fixed the particular piece of code that emitted $rdreg to make a private wire name a long time ago.

I was using "Yosys 0.9+4081 (git sha1 b6721aa, gcc 8.3.1 -fPIC -Os)" inside the openlane docker .. I see there is a new version of yosys available, i will cross-check on the same. Yosys 0.9+4249 (git sha1 d8fcf1a, clang 10.0.0-4ubuntu1 -fPIC -Os)
