Designing Memories in VLSI Design Using Specific Memory Models Generated from Generic Memory Models

摘要

Memory optimization of integrated circuit (IC) design using generic memory models is presented. One method includes accessing a register transfer level (RTL) description for the IC design that includes generic memory interface calls to generic memory models for each memory instance. The generic memory call interface includes a set of memory parameters. The method also includes processing the RTL description of the IC design as a step in a design flow for the IC design by processing specific memory models for the memory instances, wherein the specific memory model for each memory instance is generated from the generic memory model using the memory parameters corresponding to the memory instance. The method can also include generating specific memory models (e.g., simulation model, timing model, and layout model) for each memory instance based on a given set of values of memory parameters for the memory instance.
