Version
2021.1 English

The Vivado® Design Suite supports simulation using third-party tools. Simulation with third-party tools can be performed directly from within the Vivado Integrated Design Environment (IDE) or using a custom external simulation environment.

Table 1. Supported Third-Party Simulators
Third-party Simulators Red Hat 64-bit Linux Windows 10 64-bit
Siemens EDA ModelSim SE Yes Yes
Siemens EDA Questa Advanced Simulator Yes Yes
Cadence Incisive Enterprise Simulator Yes NA
Cadence Xcelium Parallel Simulator Yes NA
Synopsys VCS Yes NA
Aldec Active HDL NA Yes
Aldec Riviera PRO Yes Yes

The Vivado Design Suite User Guide: Using the Vivado IDE (UG893) describes the use of the Vivado IDE.

Please set the following environment variables before running simulation in Vivado IDE.

  1. Tool installation path should be added to environment variable PATH (irrespective of OS). To simulate SystemC based designs for the supported simulator, provide the required g++ version installation path as mentioned in SystemC Support in Vivado IDE. The LD_LIBRARY_PATH should also include simulator library path.

For links to more information on your third party simulator, see Links to Additional Information on Third-Party Simulators.

Important: Use only supported versions of third-party simulators. For more information on supported Simulators and Operating Systems, see the Compatible Third-Party Tools table in the Vivado Design Suite User Guide: Release Notes, Installation, and Licensing (UG973).
