The present invention discloses a method for viewing simulation signals of digital products and a simulation system, the method includes: when performing FPGA simulation on digital products, reading out all external port status data of digital products in real time and recording, meanwhile reading out all internal status data of digital products once every interval time and recording; after completing the simulation, when needing a back trace to check the data of digital products in a certain clock cycle, reading out the internal status data of digital products stored at the last time point before this clock cycle and the external port status data at said time point in the recorded simulation data; and taking the read-out data as an initial status data of the FPGA, then reading out all internal status data of digital products clock by clock until running to the clock cycle that needs to be viewed.

Method for viewing simulation signals of digital products and simulation system

The present invention discloses a method and system for processing simulation data. The method includes: simultaneously collecting the simulation waveform data of said multiple FPGAs and adding a time stamp to the waveform data of each FPGA collected in each collection period, and storing the waveform data of the multiple FPGAs in the form of a link list according to the time stamp. The technical solution of the present invention can ensure no disorder of the waveform data of multiple FPGAs.
