After:

Support targets:

• RISC-V 32/64 with M/A/F/D
• LoongArch32
• Mips/Mipsel 32

Usage

1. Highlight the signals you want filtered
2. Edit->Data Format->Translate Filter Process->Enable and Select
3. Click Add Proc Filter to List
4. Open file
5. Select filter filename from list $\color{red} {❗IMPORTANT❗} $
