Debugging Apparatus Using Both Very Large Scaled Digital System Realized in Hardware and Simulation and Debugging Method For Verifying Ultra Large Design

摘要

PURPOSE: A debugging device and a method are provided to make an application of a design verifying method mixed by an emulation with a simulation of a large-sized digital system possible although a scale of a design verification-objected circuit is exceeded to a limit of the simulation in a design verification for mixing the emulation with the simulation thereof. CONSTITUTION: An extended circuit capable of performing an input/output probe is automatically created by adding a probe additional circuit for an input/output probe to a design verification and a check-objected circuit. An input/output probe interface module(26) connects a hardware board embodied by the extended circuit in a hardware chip to server computers(20), controls a performance of the hardware board, performs an input/output probe with respect to the hardware chip on the hardware board in a specific time or a specific condition, and exchanges performance result information with respect to a design verification and a check-objected entire circuits or a partial circuit between the server computer(20) and the hardware chip rapidly. An emulation and a simulation are performed at least one times automatically alternately using the server computer(20) and a predetermined simulation server computer for simulating the design verification and the check-objected entire circuits or the partial circuit. Thus, an effective debugging is possible.
