Problems solved by technology

If the relevant personnel are missing, it will cause interaction delays, waste time, and reduce work efficiency. Due to the long running time of the digital back-end design process, in the final stage before tape-out, if the back-end design process is not started in time and the design results are checked, it will be difficult. affect the progress of the entire project
However, the existing technology cannot timely start the digital back-end design process according to the update of the front-end files

Abstract

The invention provides an integrated circuit designing method and apparatus. The integrated circuit designing method includes the steps of regularly detecting the updating situation of front-end files, and executing a predetermined digital rear-end designing flow through a rear-end designing tool in a predetermined execution means according to the front-end files to update the design of an integrated circuit when the front-end files are updated. The problem that digital rear-end design flow can not be timely started according to the updating situation of front-end files in the prior art can be solved, so that the design result can be timely checked by rear-end workers to advance the progress of an entire project.

Description

technical field [0001] The invention relates to the field of integrated circuit chip design, in particular to an integrated circuit design method and device. Background technique [0002] In the chip design process, it is necessary to continuously find problems and adjust the design according to the problems, and there is an interaction between the digital front end and the back end. In the existing interaction process, usually after the digital front-end personnel update the netlist (netlist) or constraints (sdc), the digital back-end personnel are notified, and then the digital back-end personnel restart the design operation according to the updated netlist or constraints process. If the relevant personnel are missing, it will cause interaction delays, waste time, and reduce work efficiency. Due to the long running time of the digital back-end design process, in the final stage before tape-out, if the back-end design process is not started in time and the design results a...
