  • Patent number: 9454636
    Abstract: In one aspect, a method for providing design point recommendations for an integrated circuit (IC) design is disclosed. The method comprises receiving an IC design along with a reference PPA (power, performance, area) metric at a reference design point, and a target PPA metric. The method also comprises estimating trial PPA metrics for the IC design at multiple design points, wherein estimating trial PPA metric at each design point includes accessing a PPA database containing PPA metrics for multiple test components, determining scale factors from the reference design point to the trial design point for test components equivalent to components of the IC design, and applying the scale factors to the reference PPA metric to determine the trial PPA metric for the trial design point. The method further comprises recommending a trial design point based on the estimated trial PPA metric and the received target PPA metric.

  • Publication number: 20160246909
    Abstract: 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.
