Spectre2Hspice.pl transforms a cell source file into a characterization Hspice source file. In this file, we need to specify the entry points of the delay look up table. The part of the file is shown below:
"#" is the reference symbol in Perl script. The resulting Hspice source file measures the delay from 50 percent of the input swing to 50 percent of the output swing. The transition is from 10 percent to 90 percent for rising, 90 percent to 10 percent for falling. In Spectre2Hspice.pl, it is specified as below:
The resulting Hspice file(for nand2x1) is as follows:
