Techniques to Boost Incisive Simulation Performance

Comments(0)Filed under: Incisive Enterprise Simulator (IES), performance, simulation speed, Accleration

Functional verification is the biggest challenge in delivering more complex electronic devices on increasingly aggressive schedules. Every technique for functional verification relies on a fast simulation engine for execution, so performance is of prime importance to all users.

Simulation performance can't be a single number or optimization because each environment is unique in terms of the methodology deployed, the languages involved, the size of the design, and the verification environment.

Hence, Cadence Incisive performance team has developed a handbook to cover the major aspects of Simulator performance. It leads users to follow certain steps to better understand, and then address the performance need.

In many situations, the steps to localize the performance bottleneck and resolve it take a considerable amount of time. The application notes in the handbook help speed this process by giving you the information to improve performance.  In the cases where you need more performance than the notes provide, they will guide you to create the well articulated and defined performance requirement making it easier for Cadence to optimize Incisive for speed.

Here is a series of application notes that focuses on areas (techniques and technologies), which helps you in improving the performance with Incisive Simulator.
