Are there commands similar to synopsys's save_session and load_session in RTL Compiler.
View ArticleScan mode and scan chain control from internal registers
Hi, I have unique requirement that scan mode be set by internal register which would control output at PO. By default PI/PO which drives scan are set for something else. Before scan starts, I need to...
View ArticleHow do I delete clock groups (created via set_clock_groups)
Hi,I have been using set_false_paths between clocks, and found out that it is better to use clock groups using set_clock_groups. Therefore, I updated my SDC files, but I now have a slight issue. I use...
