VHDL 2008 training course is a valuable resource that introduces the changes and enhancements added by IEEE Std. 1076-2008. The training is structured in three sections which cover design creation, verification with PSL assertions and functional coverage by means of Open Source Verification Methodology. We describe the features, illustrate them with examples, and show how they improve the language as a tool for design and verification. Wait no more - accelerate your projects with the ultimate language enrichments right away.

Functional Verification . Assertion Based Verification
PSL Property Specification Language:
  • Layers: Boolean ;Temporal ; Properties ;Directives ;Assertion units
  • Assertions vs. Properties
  • The notion of time
  • Operators: Always and never; The next operator; The until and before operators; SERE ;Suffix implication |-> and |=>; Weak and strong SEREs;
  • Vunits: How to associate vunits to VHDL entity/architecture ;How to associate vunits to Verilog modules (if the design contains Verilog modules)
