Practice of LPE Rule File Generation by Exact<\/strong><\/h1>\n

Introduction<\/strong><\/p>\n

This article will show how you can create LPE rule files using\u00a0EXACT<\/em><\/strong>\u2019s\u00a0LISA<\/em><\/strong>\u00a0scripting functionality. We will concentrate on generating a technology file for parasitic capacitance extraction with\u00a0HIPEX-C.<\/strong><\/em>\u00a0The same principals can be applied to other rule-base LPE tools.<\/p>\n

The Structure of a\u00a0LISA<\/em>\u00a0Script to Generate LPE Rule Files<\/strong><\/p>\n

EXACT<\/em><\/strong>\u00a0generates an LPE rule file for parasitic C extraction which contains two parts: one is for overlapping capacitances between a pair of layers, and the other is for lateral capacitances for a single layer. You can write a\u00a0LISA<\/em><\/strong>\u00a0script for each of those parts separately for easier maintenance.<\/p>\n

EXACT<\/strong><\/em>\u00a0allows you to use the LOAD command to execute multiple\u00a0LISA<\/em><\/strong>\u00a0scripts to generate LPE rule files separately. You can merge those generated rule files using a shell command such as \u201ccat\u201d. You can use those shell commands with the\u00a0LISA<\/em><\/strong>\u00a0function \u2019sh(\u201c<shell command>\u201d);\u2019 in your script. See Example 1.<\/p>\n

You can write some description independent of\u00a0EXACT<\/strong><\/em>\u2019s simulation, such as comments or layer derivation commands, using the WRITE command in\u00a0LISA<\/em><\/strong>\u00a0directly. You can merge those descriptions prepared as another separate text file.<\/p>\n<\/div><\/section><\/div>
