Description

technical field [0001] The invention belongs to the field of integrated circuit design, relates to field programmable logic device (abbreviated as programmable logic device) integrated circuit software tool design technology, in particular to a programmable logic device and its memory management system. Background technique [0002] When the programmable logic device executes the routing algorithm process (including the serial routing algorithm process and the parallel routing algorithm process), it will call the routing data in the memory (memory) of the programmable logic device. If the memory of the programmable logic device can be efficiently managed The routing data can greatly improve the development efficiency of routing algorithms, thereby speeding up the overall routing process. [0003] Most of the existing programmable logic devices use serial flow for integrated circuit design. In order to be suitable for the serial wiring algorithm flow when the programmable log...

Problems solved by technology

Therefore, the way the programmable logic device manages the memory is relatively chaotic, and it is still prone to access conflicts caused by too many critical resources, which also makes the development efficiency of the routing algorithm in the integrated circuit design process low, thereby slowing down the overall routing process. process
