Underlying hardware mapping method for integrated circuit as well as time sequence constraint method and device for data control flow

Abstract

The invention discloses an underlying hardware mapping method and device for an integrated circuit, wherein a computer language program describing the algorithm of the integrated circuit is analyzed, mapped into a data control flow graph and further converted into an operator time-space diagram; and the time sequence constraint is carried out on the data control flow graph, then the clustering compression is carried out on the operator time-space diagram according to a time sequence label, and the logical description on the underlying hardware circuit of the integrated circuit is further generated, thereby creating a mapping tool from computer language to the underlying hardware circuit of the integrated circuit, realizing the process of generating underlying hardware of the integrated circuit from C or MATLAB (matrix laboratory) and other languages in a standardized manner conveniently and fast. The invention also discloses time sequence constraint method and device for a data control flow graph, wherein the circuit obtained according to the constraint method is ensured to have regularity by carrying out the time sequence constraint on the data control flow; and furthermore, the method is applicable to time sequence design and verification of a digital circuit and can be favorable for a hardware engineer to carry out hardware design to a greater extent.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to an integrated circuit lower layer hardware mapping method, a data control flow timing constraint method and a device. Background technique [0002] In the field of integrated circuits, the design speed of integrated circuits usually lags behind the development speed of integrated circuit manufacturing processes. Especially after the manufacturing process of integrated circuits has entered the nanometer level, the design speed of integrated circuits has lagged far behind the development speed of integrated circuit manufacturing processes. Therefore, for the field of integrated circuit design, improving the design speed is one of the most urgent problems at present. Such as figure 1 As shown, in the prior art, the design of an integrated circuit usually includes two parts: the first part is from the algorithm description based on C language or MATLAB language to the descr...
