Problems solved by technology

[0002] The IEEE1394b-2008 bus protocol stipulates a lot of physical layer time parameters, and some parameters have longer time requirements. Among them, the handshake time RECEIVE_OK_HANDSHAKE, the connection detection time CONNECT_TIMEOUT, the speed negotiation time TONE_DURATION, and the reset detection time RESET_DETECT are all at the ms level. Verification, especially the post-simulation of the circuit netlist is very time-consuming, making the simulation progress unacceptable

Abstract

The invention belongs to the field of computer hardware control and relates to a method for accelerating 1394 physical layer virtual simulation. The invention scales the time characteristic specified by the 1394 physical layer, which can not only ensure that the time characteristic test required by the 1394 physical layer is sufficient, but also speed up the simulation verification time. The invention comprises a 1394 physical layer circuit protocol test platform (1) and a group of original 1394 physical layer time parameters (2); a group of proportionally reduced 1394 physical layer time parameters (3); parameter selection setting (4) ; Described 1394 physical layer circuit protocol test platform (1) chooses to use a group of proportionally reduced 1394 physical layer time parameters (3) to carry out 1394 physical layer virtual verification and can accelerate the virtual verification process under the control of parameter selection setting (4) ; The 1394 physical layer circuit protocol test platform (1) selects and uses a group of original 1394 physical layer time parameters (2) under the control of the parameter selection setting (4) for circuit physical realization.
