which software application published by 'Aldec' has a feature/module/file called 'RIVIERA_VHPI_SUPPORT? What is RIVIERA_VHPI_SUPPORT?

The software application published by Aldec that includes the feature called `RIVIERA_VHPI_SUPPORT` is **Riviera-PRO**. `RIVIERA_VHPI_SUPPORT` refers to support for the VHPI (VHDL Procedural Interface) standard, which allows for integration of VHDL simulation with external procedural languages like C or C++. This support enables users to create more complex simulations by allowing external programs to interact with the VHDL simulation environment, facilitating tasks such as creating custom test benches or performing advanced modeling and verification tasks. In summary, `RIVIERA_VHPI_SUPPORT` is a key feature within Riviera-PRO that enhances simulation capabilities by bridging VHDL with procedural languages.
