At this point it must be stated that the compilation of the source code can either be done within the simulation environment (GUI) or on the command prompt. This enables each individual unit of the entire simulation to be compiled independantly and incremental compilation to be performed. The Questa tool enables compilation of multiple design/verification/modeling units (each of which might be in a different language) into a common library (called the working library) and a common design representation. If not, the information can be obtained from the remote access page.

It is assumed here that user is aware of the requirements for remote access from a Windows platform. set environment variable MODELSIM to modelsim.iniĪt this point, all the path settings are good to go for the executables associated with Questa.You would still need to run the following commands each time you start a set of simulations for a given design within a directory. Let us assume a directory has been setup up correctly and you come into this directory for a future simulation. We assume the previous step has already been followed. Setup for simulations within a directory for a given session:.Note that in some cases, if the compilation seems to crash for a reason you think is incorrect, it would be advisable to delete the “mti_lib” directory (Use: \rm –rf mti_lib OR vdel –all) and re-create it as shown above.

(Note that the name “mti_lib” corresponds to the variable “work” within the modelsim.ini file and is the library to which all the source code would be compiled to create a design single entity).

Create the library into which all the design units will be compiled.

This file sets up the necessary defaults for the Questa tool.

Copy the modelsim.ini file that comes with this tutorial into the directory.

Prompt%> add questasim63 OR prompt%> add modelsim

One time setup for a given directory used for simulation:Įach time you create a directory for simulations you would have to do the following.

This is going to be done using the example of a modified DLX execution block with a 2-stage pipeline.Įstablishing the Design Environment for compilation The aim of this tutorial is to understand the basics of working with SystemVerilog in the Questa tool environment.

This tool is an advancement over Modelsim in its support for advanced Verification features like coverage databases, coverage driven verification, working with assertions, SystemVerilog constrained-random functionality. The tool provides simulation support for latest standards of SystemC, SystemVerilog, Verilog 2001 standard and VHDL. QuestaSim is part of the Questa Advanced Functional Verification Platform and is the latest tool in Mentor Graphics tool suite for Functional Verification. 2 Establishing the Design Environment for compilation.
