[Auto P&R] Innovus cmd 활용하기

innovus cmd 파일을 활용하여 Linux환경에서 Setup을 설정하는 방법을 알아보도록 하겠습니다.

먼저 ls로 list를 확인 한 후, vi innovus.cmd로 필요한 파일이 무엇인지 찾아줍니다.

 

필요한 .cmd파일을 찾았다면 

[pnr_108@npit-digital-rnd pnr]$ iv run_spi.scr

run_spi.scr이라는 Script를 만들어 여기에 커맨드를 저장해주겠습니다.

Setup

 

#Design Import

set init_verilog ../syn/outputs/spi_netlist.v
set init_lef_file ../lib/lef/all.lef
set init_pwr_net VDD
set init_gnd_net VSS
set init_mmmc_file Default.view
set_global _enable_mmmc_by_default_flow      $CTE::mmmc_default
init_design

#Floorplan

#Powerplan

#Placement

#CTS & Route

#Filler Insert

#Verify

#GDSII

일단 Design Import 부분만 위처럼 저장해주었습니다.

 

내부에 Setup이 위와같이 지정된 모습을 볼 수 있습니다.

Floor Plan

다음으로 하나씩 Floorplan과 동일한 방식을 진행하며 cmd파일을 확인합니다.

그 후 동작에 맞는 code를 run_spi.scr파일에 추가합니다.

 

Floorplan 단계를 거치고 .cmd파일에 기록된 동작도 run_spi.scr에 추가합니다.

#Floorplan

Execute

cmd에서 가져온 명령어 Script 실행

[pnr_108@npit-digital-rnd pnr]$ innovus -files run_spi.scr

 

이러면 한 번에 모든과정을 실행한 Innovus를 실행할 수 있습니다.
