5.2.2. Simulation Scripts

The Quartus® Prime software generates simulation scripts during project generation for several different third party simulation tools—Cadence, Synopsys* , and Siemens EDA.

The simulation scripts are located under the sim/ed_sim directory, in separate folders named after each supported simulator.
