    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

  • Patterns Library
    The Verification Academy Patterns Library contains a collection of solutions to many of today's verification problems. The patterns contained in the library span across the entire domain of verification (i.e., from specification to methodology to implementation—and across multiple verification engines such as formal, simulation, and emulation).

Sequence

A class-based representation of one or more stimulus items (Sequence Items) which are executed on a driver. Can collaborate in a hierarchy for successive abstraction of stimulus and can participate in constrained random setup to enable highly variable sets of stimulus above the randomization possible in an individual transaction. Sequences can represent temporal succession of stimulus, or parallel tracks of competing or independent stimulus on more than one interface. They can be built up into comprehensive stress test stimulus or real world stimulus particular to the needs of the protocol. UVM has comprehensive support the automated definition and application of sequences.

In its simplest form, a sequence is a function call (a functor), which may request permission to communicate with a driver using a sequence item. This complicated sounding interaction is not so complicated. A sequence asks for permission to send a transaction (sequence item) to the driver. Once it has been granted permission by the sequencer, then the transaction is passed to the driver.
