Abstract

The invention discloses a logic comprehensive control method and device. The logic comprehensive control method comprises the steps of detecting whether an initial value of a memory in a read RTL design file is changed or not; when the detection result is yes, according to a pre-established mapping relationship, correspondingly modifying an initial value of a memory instance in a synthesized netlist obtained by executing logic synthesis operation on the RTL design file most recently so as to update the synthesized netlist, wherein the mapping relationship is used for representing a corresponding relationship between the initial value of the memory in the RTL design file and the initial value of the memory instance in the synthesized netlist obtained by performing logic synthesis operationon the RTL design file last time. Obviously, according to the method, under the condition that the initial value of the memory in the RTL design file is changed, only the initial value of the memory instance in the synthesized netlist needs to be correspondingly modified according to the pre-established mapping relation, logic synthesis does not need to be carried out again, logic synthesis time can be shortened, and the development and design efficiency of the FPGA is improved.

Description

technical field [0001] The invention relates to the field of FPGA technology, in particular to a logic synthesis control method and device. Background technique [0002] Artificial intelligence is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. It is the core driving force of a new round of industrial transformation and a new engine of economic development. As a general-purpose programmable logic device, FPGA is designed closer to the underlying hardware architecture, has a large number of RAM resources, DSP resources, etc., is good at data parallel computing, more flexible and low-latency, and also has power consumption. Low cost, programmable and flexible design. Based on this, FPGA has been widely used in many application fields of artificial intelligence. [0003] In the practical application of applying FPGA to the field of artificial intelligence, aft...
