Neither do I think it's a bug that RTL Compiler adds five- or six-digit random number suffixes to module names during uniquify and there must be good reasons for C company to do so.<br /><br />It's fine with me, but not fine with our DfT tool. Our aged DfT tool needs a fixed list of bistshells and clock gating cells and can't work even one module name is changed. Instead of bistshell_32898 and bistshell_236840, bistshell_0 and bistshell_1 are more preferred.<br />Previously I fix the names by sed script that is too time consuming as module names inscrease, so I ask for a RC script from C Company. I received a script yesterday, played with it and wrote a new one this afternoon.<br /><br />It's very simple. You can modify and redistribute it freely. Please notice that the scripts is provided "as is". I have tested it with one big subdesign. However, as an IC designer, I have to reminde that YMMV, :-P<br /><br />Download: <a href="http://my.6to23.com/sthabouticdesign/change_uniq_name.tcl">change_uniq_name.tcl</a><br /><br />Usage: after uniquify and map, source the script in rc and call procedure "change_uniq_name".<br /><br />Suggest: At the first time, comment line 63 "mv $module_name ${x}_${count}" and redirect output to a log file. The file will list both original name and target name of every module that will be modified. Please Check it carefully. If everything is OK, uncomment and go!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5796168-115824580876263104?l=chenboliu.philewar.org' alt='' /></div>Chenbohttp://www.blogger.com/profile/15610707537902254226noreply@blogger.com0
