Chip register automatic development system based on template variable replacement

Abstract

The invention relates to an automatic chip register development system based on template variable replacement. The automatic chip register development system comprises an input file; the input file comprises a register document file, an RTL code, UVM verification, a control parameter file in C and C + + formats, and a template file in an output file format; in a register document file, registers are subjected to level-to-level management, and three levels including a chip level, a module level and a register group are included; according to the method, a Python programming language is used for generating a Python class for each register, a register group and a module level, namely a chip level. Meanwhile, code generation control parameters are converted into the Python classes, then different template files are called, register variables in template level files are replaced according to control parameter values, and finally design, verification and debugging codes of the chip registers are automatically generated.

Description

technical field [0001] The invention belongs to the technical field of digital logic chip development, in particular to a chip register automatic development system based on template variable replacement. Background technique [0002] Since the emergence of digital logic integrated circuit technology in the 1960s, the scale of chips has become larger and larger. At present, the number of transistors in a single chip of VLSI can reach the scale of several billion gates. At the same time, the number and types of internal registers in the chip have also increased significantly with the simultaneous increase in the scale of digital and mixed logic chips. For ultra-large-scale chips, the number of registers can reach hundreds of thousands, and what is even more frightening is the types of registers. There are more than 50 types of commonly used registers, and new types of special registers are constantly being produced. How to quickly and efficiently complete the development of c...

[0005] The Chinese patent "Method and System for Automatic Generation of Chip Register Codes" (application date 2015.09.30; authorized announcement number CN 105607897 B) discloses an automatic generation system for chip register codes. The solution is to use VisualBasic to call register description files to extract all The register parameters in the above register description document, the biggest problem of this solution is the narrow coverage, and the development efficiency needs to be improved

Chinese patent "Register Automatic Verification Method Based on VMM RAL" (application date 2012.11.27; application publication number CN 103838653 A) discloses an automatic register verification system. Although the actual use of this scheme has a large coverage, the development efficiency is very low

[0006] To sum up, the scale of the chip is getting bigger and bigger, the R&D process is getting longer and longer, the number of large-scale chip registers is tens of thousands, and the workload of designing, verifying and debugging the registers is increasing. The register automatic development system with large scope, high development efficiency and short cycle has become a technical bottleneck for those skilled in the art
