Breakdown will occur when the voltage bias between some terminals of an element is too large. The .BIASCHK statement monitors the voltage bias with user defined limits and noise. Bias monitoring can check the bias that you want to monitor during transient analysis and report the following:
The information will be saved as a warning and biaschk summary in the *.lis file.
This command is for MOS only in Star-Hspice release 2001.2. BIASCHK cannot detect the bias exceeding the limit if the bias is always the same value during transient analysis.
