In this post we look at how we use VHDL to write a basic testbench. We start by looking at thearchitecture of a VHDL test bench. We then look at some key concepts such as thetime typeandtime consuming constructs
In this post we look at how we use Verilog to write a basic testbench. We start by looking at thearchitecture of a Verilog testbenchbefore considering some key concepts in verilog testbench design. This includesmodelling time in verilog, theinitial block, verilog-initial-block and theverilog ...

In my example, in the top level file (microP vhdl file), i have 3 instances of the register component (inst_reg_A, inst_reg_B and inst_reg_Adr). The register component include a signal 'reg'. So my question is how to specify in the vhdl testbench file that i...
I have a verilog project,and already run and got my .vo file,now someone else want to write a VHDL testbench for my project to implement a whole scheduling emulation,how? ie: my verilog module name is im1,if i write COMPONENT im1 PORT ( XXXX:XXXXXX...

A failsafe and universal way to stop a VHDL testbench is to create an assertion failure. That was the first way someone taught me to end the simulation when I was learning VHDL at the university. No additional imports are needed, and it works in all VHDL versions. Just make sure to use...
Run the command below in the Tcl console to create the Testbench for the BD: tclapp::xilinx::designutils::write_ip_integrator_testbench -addToProject Note: There is a known issue in the tools where the Synthesis ELF will over-write the Simulation ELF. ...
These waveforms can be used as custom stimulators by assigning them to the desired signals. Graphically edited waveforms can also be used as simulation input in conjunction with the TestBench Wizard, described later in this document, which generates a VHDL or Verilog test program that is based ...
