Simulation and verification device and simulation and verification method based on TCL

Abstract

The invention provides a simulation and verification device and a simulation and verification method based on a TCL. A TCL control platform is used as an excitation data and control order transmitting terminal, a debugging order and data, which are programmed by virtue of a scripting language, are transmitted by the TCL control platform to a to-be-detected simulation platform, then the to-be-detected simulation is driven in a task form to run, not only can the excitation data be transmitted to the simulation platform, but also the branch control can be carried out by virtue of the verification excitation of feedback data and interruption information of the simulation platform, after the simulation platform is operated, the well-programmed TCL script or a single order is started, the simulation operation is controlled in real time, the simulation result is monitored in real time, the coding time is short, and the real-time interaction with the simulation platform in the simulation process can be realized.

Description

technical field [0001] The invention relates to the field of simulation verification, in particular to a simulation verification device and method based on TCL (Tool Command Language, tool command language). Background technique [0002] At present, the simulation methods for the model to be verified mainly include: direct excitation simulation, CPU-driven simulation and FPGA (Field-Programmable Gate Array, ie Field Programmable Gate Array) simulation. [0003] Direct excitation simulation is to write test cases according to the input port timing of the model under test in the test platform, directly drive the model under test for simulation, and sample the output data at the output end for comparison. The disadvantage is that every time the test case is modified, the entire test platform must be recompiled and then the simulation is executed, which makes the entire simulation, debugging, and modification cycle very long. [0004] The CPU-driven simulation includes two situ...
