hello everyone
When I simulated PLL, aps simulation could converge, but when I put ++aps on the hook, vco did not vibrate.
Meanwhile, if XPS ms is used, the following error occurs:
Internal error found in spectre in "pmos_rf_lvt_5t":' i0. I0XXXXXX'...During hierarcht flattening, furing circuit read - in. Encountered a cirtical error during simulation.
