Hi, Can you set the 'Post-Layout Preset Mode' to 'Legacy-RF RCR' instead of 'Legacy RCR' ? This will print +postlayout=legacy_rf out in the spectre command in the spectre.out log file. The legacy_rf is recommended to be used for RF analyses like pss as it uses algorithm dedicated for RF usage. If the sim is still hanging, try to move to a latest spectre version as you are using an old one. The latest release is Spectre 17.1.0.198.isr3 at the moment . Keep legacy_rf to run the simulations. If the problem still insists, then I'd recommend you to file a ticket on customer support and provide your testcase. If you cannot provide a testcase then give information about the design that is used, the pss settings and any other settings/log files you have but it's hard to debug this without a testcase.
