Assertions using SystemVerilog (SVA) - Foundation course
What is SystemVerilog Assertion (SVA)?
SVA is an integral part of IEEE-1800 SystemVerilog languages focusing on the temporal aspects of specification, modeling and verification. SVA allows sophisticated, multi-cycle assertions and functional checks to be embedded in HDL code. SVA allows simple HDL boolean expressions to be built into complex definitions of design behavior, which can be used for assertions, functional coverage, debug and formal verification.
Overview
CVC’s ABV SystemVerilog course gives you an in-depth introduction to the language, together with guidelines and methodologies to help you create, manage and debug effective assertions for complex design properties. The course is packed full of examples and case studies to demonstrate real life applications of the language.
Objectives
To explain the advantages of Assertion Based Verification (ABV) using the System Verilog Assertions (SVA).
To describe in detail the boolean, temporal, verification layers of SVA and show how the layers are used to build assertions.
To demonstrate, with examples, good and bad SVA coding styles and show workarounds for simulators with language support issues.
Prerequisites
Delegates must be able to read, write and understand VHDL or Verilog code, and be familiar with running and debugging HDL simulations. This training assumes no prior knowledge of SVA.
