APPROACHFOR LOGIC SIGNAL GROUPING AND RTL GENERATION USING XML

摘要

Systems and methods for generating an RTL description based on logical signal groupings are described. Logical interfaces are declared in a compressed form, and logical signal grouping is defined in a markup document. The definitions from the markup document are used by expansion scripts to populate RTL modules and encapsulate block connectivity and functionality. Multiple interfaces can be created instantly, and interface definitions for common interfaces may be easily re-defined. Default values may be assigned to module outputs for testing purposes, allowing for multi-module simulations where certain modules are shelled-out.

1. A method for generating a register transfer level (RTL) description using logical signal grouping, the method comprising:
generating a plurality of logical interface definitions, wherein the logical interface definitions define signals from an output module to an input module and comprise an interface rule; defining a data structure in a structured document, wherein the data structure comprises a first set of logical interfaces; and executing an expansion script to generate an RTL description using the structured document, wherein the RTL description comprises a plurality of RTL modules that communicate using the logical interface definitions, and wherein the RTL description is populated based on the logical interface definitions, the interface rule, and the data structure.
