Embodiment Construction

[0012] The software condition monitoring of power consumption analysis in the described digital circuit and the wave file automatic generation method comprise the steps:

[0013] Step 1, according to the power consumption analysis requirements, extract and analyze the conditions of the software pattern, fill in the excel form in the specified format, and generate a file of register configuration information through script processing, which is used as the theoretical value for comparison during monitoring.

[0014] Step 2. Perform EDA simulation for the software pattern provided by the power consumption analysis, read in the monitored theoretical value file, and automatically check and compare the factors affecting power consumption during the simulation process. If the check passes, go to step 3. If the inspection result does not match the theoretical value, report ERROR (error), and print out specific information, debug the software, re-simulate after modification, and repeat ...

Abstract

The invention discloses an automatic generation method of a software condition monitoring and wave file for power consumption analysis in a digital circuit. The automatic generation method comprises the following steps: 1) according to power consumption analysis requirements, carrying out extraction analysis on the conditions of a software pattern, filling in an excel table of a prescribed format, generating a register configuration information file through script processing, and taking the register configuration information file as a comparison theoretical value during monitoring; 2) carrying out EDA (Electronic Design Automation) simulation on the software pattern provided by the power consumption analysis, reading a monitoring theoretical value file, and carrying out automatic checkout and comparison on factors which affect the power consumption in a simulation process; and 3) according to the power consumption analysis requirements, determining the start and the stop of an exported wave according to the register configuration or signals in the simulation process, and directly exporting the wave file for power consumption analysis. A workload can be greatly saved, and working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of power consumption analysis in digital circuits, in particular to a method for monitoring software conditions and automatically generating waveform files for power consumption analysis in digital circuits. Background technique [0002] Power consumption analysis is very important for chip performance evaluation. The traditional method of providing power consumption analysis waveforms is to manually view the simulated waveform files to confirm that the software configuration of the running program meets the requirements of power consumption analysis, and then segment the simulation waveform files as required for power consumption analysis. enter. As the chip design becomes more and more complex, more and more integrated IP (Intellectual Property, intellectual property rights) are added, and the application scenarios become more and more diverse, and the workload of power consumption analysis also increases according...
