The CAM IP generator core provides a quick way to simulate and observe the behavior of the core by using the provided example design, which has a self-checking test bench that uses System Verilog Direct Programming Interface (DPI). It is recommended that you familiarize yourself with Section 35 of IEEE 1800-2017 to gain a more complete understanding of its functionality.

  1. In the new Example Design Vivado project, change the target simulator:
    1. Click Settings under the PROJECT MANAGER section in the left-hand panel. The Settings window displays.
    2. Select Simulation under Project Settings, and select the target simulator you want to use, as shown in the following figure.

  2. Verify that the compiled library location is set correctly and points to the correct pre-compiled simulation libraries for the simulator being used. See the Vivado Design Suite User Guide: Logic Simulation (UG900) for instructions on how to compile simulation libraries.
Note: When the example design for the CAM IP is generated, a simulation SystemVerilog package file is also created with the name <instance-name>_sim_pkg.sv. This file contains the SystemVerilog taskcreate which contains the configuration settings used for this particular CAM IP instance.

Optional Features

Backdoor feature
This feature speeds up simulation runtime when enabled for behavioral simulations only. This feature is disabled by default. To enable this feature, perform the following edit to the file:
axi_lite_master.sv
Set the define CAM_BACKDOOR
Dump Memory feature
This feature allows memory contents to be dumped at the end of the test for behavioral simulations only. This feature is disabled by default. To enable this feature, perform the following edit to the file:
example_top.sv
Set the parameter DUMP = 1;
