Using the HSPICE Transient Controller

The HS_Tran controller is available on the Signal Integrity-Verification component palette. When using the HS_Tran controller, other controllers such as DC or AC cannot be present in the design. Also, no DSP cosimulation is allowed such as an ADS Ptolemy cosimulation. If an additional controller is present, the simulator will terminate the simulation with an error message.

The unencrypted portion of the design can contain only linear devices, and selected voltage and current sources. The following table lists the allowed sources.
