Performance-Aware e Coding Guidelines – Part 4

Comments(0)Filed under: Functional Verification, OVM, IES, e, Specman, IEEE 1647, OVM e, IES-XL, tech tips, OVM-e, API, specman elite, performance, sequences

Specman 8.2s3 contains a new API to the sequence driver that enables users to improve the performance of stimulus creation.  With this API you can create stimulus items in an efficient manner, and reduce the number of context switches between the sequence and its driver. For example, instead of many generation actions, you can simply send items from a list:

for each in input_list {


There are many more use models of the Sequences API, and you’ll find many detailed examples in the OVM User Guide.

Until the next & final segment of the series (where I’ll discuss Temporals), happy coding!
