[SKILL] 원클릭으로 LVS 돌리기

예전 작성했던 글중 인기 많았던 씨리즈(?)인 원클릭으로 LVS 돌리는 방법이다. 역시나 몇 년이나 지난 만큼 최근 사용하는 코드는 많이 업그레이드 되었지만, 기록 차원에서 남겨둔다. 새로운 강좌글을 작성할 때 기초 단계 정도로 참고할 수 있을 것 같다. 방식은 export GDS, CDL 등과 유사하다. template 파일을 작성하고 ipc (inter process communicate)를 통해 calibre LVS를 실행하게 된다.

procedure(run_lvs()
   prog(()
      cv=hiGetCurrentWindow()->cellView
      _RUNDIR=getWorkingDir()

      ipcProcess=ipcBeginProcess(sprintf(_tmp, "mkdir %s/../VERIFY/LVS/%s", _RUNDIR cv->cellName))

      out_file1=outfile(sprintf(_tmp "%s/../VERIFY/LVS/%s/_source.net_" _RUNDIR cv->cellName))
      fprintf(out_file1 ".INCLUDE \"%s/../VERIFY/RULE/source_added\"\n" _RUNDIR)
      fprintf(out_file1 ".INCLUDE \"%s/../VERIFY/NET/%s.net\"\n" _RUNDIR cv->cellName)
      close(out_file1)

      out_file2=outfile(sprintf(_tmp "%s/../VERIFY/LVS/%s/_calibre.lvs_" _RUNDIR cv->cellName))
      fprintf(out_file2 "LAYOUT PATH  \"%s/../VERIFY/GDS/%s.gds\"\n" _RUNDIR cv->cellName)

      fprintf(out_file2 "LVS IGNORE PORTS NO\n")

      ipcProcess=ipcBeginProcess(sprintf(_tmp, "cd %s/../VERIFY/LVS/%s ; calibre -lvs -hier -turbo -turbo_litho -hyper -nowait %s/../VERIFY/LVS/%s/_calibre.lvs_", _RUNDIR cv->cellName _RUNDIR cv->cellName))

      ipcWait(ipcProcess)

      ipcProcess=ipcBeginProcess(sprintf(_tmp, "calibre -rve -lvs %s/../VERIFY/LVS/%s/svdb", _RUNDIR, cv->cellName))
   )
)

ipcWait 를 걸게 되면 virtuoso 환경이 해당 기능이 종료될 때까지 멈추게 된다. 작은 Block 이라면 금방 끝나겠지만, 오래 걸릴 경우 비효율적이 되어 최근에는 touch 기능을 이용하도록 변경하였다. 최신 방법으로 작성하는 것은 새로운 포스팅을 조금만 기다려 주시길.
