Abstract:

In order to improve the verification efficiency of coordinate rotation digital computer (CORDIC), a new verification model that derives from orthogonal statics theory is proposed. Using this model, we set up orthogonal tables with the test factors, and choose the best optimized test method to verify according to orthogonal tables results. Moreover, the proposed model can randomly generate test vectors and automatically check the precision errors of CORDIC calculation results. Simulation results show that the orthogonal model can greatly cut down verification period and improve working efficiency.

Key words: orthogonal statics, reference model, calculation precision, function verification, random
