Expert VHDL Verification (4 sessions) is for design engineers and verification engineers involved in VHDL test bench development or behavioural modelling for the purpose of functional verification. Advanced VHDL language constructs are presented using a practical testbench methodology as an example.

If it is false, it is said that an assertion violation occurred. Jim Duckworth, WPI 25 Advanced Testing using VHDL Assert Statements • During testing – Usually want to display information about signals and variables • Assert statement is rather limited – Report clause only allows a single string – no built-in provision for formatting data ASSERT FALSE REPORT “first line” & CR & “second line”; An assert is a VHDL language construct that if the statement that is passed evaluates to false, the body of the statement will execute. There is lots of information on the web about the VHDL assert construct. 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.

How can you write information to the console? I have in VHDL a code segment which makes me unsure if it's right: a and b are std_logic_vectors. c1 and c0 are std_logic. Is this correct written?

For the first   VHDL for simulation. – Simple simulation example.

VHDL is a compound acronym for VHSIC (Very High Speed Integrated Circuit) HDL (Hardware Description Language). As a Hardware Description Language, it is primarily used to describe or model circuits. VHDL is an ideal language for describing circuits since it offers language constructs that easily describe both concurrent and sequential behavior

It includes templates for VHDL modules, testbenches, and ModelSim DO scripts.

Tool: Vivado 2017.4 The issue seems to be that it doesn't correctly detect that the following construc The assert statement's report clause requires a string value. In VHDL-87,this meant that you would need to write and call a function that converts the variable type into a string VHDL-2019 was requested by users, ranked by users, scrutinized by users, written by users, and balloted by the VHDL community. As such, it should be clear to the vendor (simulator and synthesis) community that the users want these features. 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.
