These statements can be mapped to VITAL generics through well-defined transformations with elements separated by underscores. The actual selection of the timing values that are used is determined within the VHDL/VITAL model. In SDF, a conditional path delay consists of a condition applied to a ...

The optional label allows us to identify the statement. We will discuss labeled statements inChapter 20. The syntax rules tell us that we can specify a delay mechanism, which we come to soon, and one or more waveform elements, each consisting of a new value and an optional delay time. We...
IF/CASE/COND (ICC) expressions occurring within the HDL program that are not recognized by Verilog HDL are categorized and accordingly translated to IF/CASE statements in Verilog HDL syntax. For ICC expressions that are part of a conditional or binary operator expression, a globally incremental ...
When using the blocking assignment operator, the assignments to operands on the left side of the operator are completed before evaluation of expressions to the right of subsequent statements in the block is begun. Evaluation of those subsequent expressions is thus “blocked” until assignments are ...
