Dump waveform in multiple files

Say, you need to run a huge time consuming simulation that might dump an fsdb waveform with a “larger than disk” size, you have an option to let the simulator split it into multiple smaller sized files so that you can discard unwanted files if it doesn’t have what you are looking for.

$fsdbAutoSwitchDumpFile  – Automatically switch to a new dump file when the working FSDB file reaches the specified size limitation.

$fsdbAutoSwitchDumpfile(File_Size, “FSDB_name”, Number_of_Files [, log_filename]);

Example : 

$fsdbAutoSwitchDumpfile(1000,SOC_fsdb_file,20);

This will dump maximum 20 files in 1GB increments with name SOC_fsdb_file
