How does everyone use Net Rules in the Batch Analysis Spreadsheet? Has everyone generated their own set of rules across multiple parameters, or are there templates available? I understand that HyperLynx will search IBIS models for some of the rule information, but I can't say that I have every seen an IBIS model with ringback and overshoot properties. I haven't seen any of that information in a datasheet either, which makes these rule assignments complete guesswork. So what 'rules-of-thumb' do the sim-savvy use for specific IO technology or specific protocols?
