Add to Cart Overview. This comprehensive curriculum is a thorough introduction to the VHDL language. VHDL Assert Statements Model Extract 1. Concurrent or sequential VHDL-AMS assertion syntax. As examples, we can write the following VHDL-AMS assertions: Rq1: assert (ps >= 500.0 VHDL Command Summary. Concurrent Statements assert condition -- When condition is false [strng_expression] is printed. [ report string_expression ] This example starts with a full adder described in the adder.vhdl file: Check the outputs.

There are simulator vendors out there who are actively implementing VHDL-2019. VHDL-93 allows report to be used on it's own as a sequential statement, giving the same functionality as assert false, except that the default severity is note. You may want to report the value of a signal (or variable) that is not a string.

The body of the assert may contain a “report” field. This text field enables the code to print out a message to the simulation log. A common use of assert and report statements is to display information about signals or variables dynamically during a simulation run. Unfortunately, VHDL’s built-in support for this is somewhat limited. The problem is twofold: first, the report clause only accepts a single string as its argument, so it is necessary to either write multiple assert So I put an ASSERT statement into the VHDL with a FAILURE level alert.
