1.5.13.1. PVT Simulations

The automatically generated HSPICE simulation files are set up to simulate the slow process corner using low voltage, high temperature, and slow transistors. To ensure a fully robust link, Intel recommends that you run simulations over all process corners.

To perform process, voltage, and temperature (PVT) simulations, manually modify the spice decks in a two step process:

  1. Remove the double-counting compensation circuitry from the simulation file. This is required as the amount of double-counting is dependent upon how the Intel® Quartus® Prime software calculates delays and is not based on which PVT corner is being simulated. By default, the Intel® Quartus® Prime software provides timing numbers using the slow process corner.
  2. Select the proper corner for the PVT simulation by setting the correct HSPICE temperature, changing the supply voltage sources, and loading the correct transistor models.

A more detailed description of HSPICE process corners can be found in the family-specific HSPICE model documentation.
