Creating a LEF using Innovus

mak22

Hi,

Is there a link to cheatsheet or handy commands for the following purpose:

- If I know my pin IO and the layers they need to be in, is there a way to create a LEF using innovus? I feel a tcl based foreach will be easier for me to script and maintain as I am not familiar with Skill (to do it in Virtuoso XL). I don't have full layout yet to generate from my design.

- Ideally, I would like a cheatsheet or steps to say

a) I have innovus open. I would like to open a new design/blank canvas

b) create a bounding box for the block

c) create ports or pins and snap to nearest legal grid

d) save as LEF

Thank you in advance for the help.
