The invention discloses microprocessor silicone-fed verification device and method for compatibility design, and aims at solving the problems of slow test excitation generation, low verification result examination and complex control in the existing microprocessor silicone-fed function compatibility verification technology. The device is of a main-secondary double-chip structure, comprising a debugging host, a development board, a main control chip and a secondary control chip; a main control program and a secondary control program are set in the debugging host; the main control chip and the secondary control chip respectively load and operate the main control program and the secondary control program to generate and operate test excitation, then the operation results of the main control chip and the secondary control chip to the test excitation programs are compared through the main control program, and finally the verification result is displayed through the debugging host. With the adoption of the device, the verification process is free of artificial interference; a hardware platform is simple to control; the silicone-fed verification accuracy and verification efficiency can be effectively increased.
Description
technical field [0001] The invention relates to the field of post-silicon function verification of microprocessors, in particular to a device and method for computing post-silicon function verification of a compatible chip instruction set. Background technique [0002] Military microprocessors (including CPUs and DSPs) are widely used in missiles, satellites, aircraft, ships, radars, tanks, and military secure communications. Due to the large number of foreign chips imported, facing the threat of embargo and outage, and the hidden dangers of safety and reliability, it is of great significance to independently develop compatible military microprocessors and realize localization substitution. [0003] The compatibility referred to in the present invention mainly refers to self-developed microprocessors and the realization of pluggable and replaceable use of foreign microprocessors. For the convenience of description, the present invention refers to the foreign microprocessor ...
