Accelerated VIP for APB4 Protocol

The idea of using Accelerated VIP is to push the synthesizable part of the testbench into the separate top module along with the interface and it is named as HDL TOP and the unsynthesizable part is pushed into the HVL TOP. This setup provides the ability to run the longer tests quickly. This particular testbench can be used for the simulation as well as the emulation based on mode of operation.

Key Features

1. It supports addresses up to 32 bit wide.
2. APB4 support for write strobe signal to enable sparse data transfer on the write data bus.
3. Single Master - Multiple Slaves.
4. Programmable Wait state insertion.
5. Slave supports fine grain control of response per address or per transfer.
6. Programmable character length(multiple of 8 bits).
7. Supports protected access.
8. Random PSLVERR insertion.
9. Supports sending of completely configured data.

Running the test

Using Mentor's Questasim simulator

cd apb_avip/sim/questasim

# Compilation:  
make compile

# Simulation:
make simulate test=<test_name> uvm_verbosity=<VERBOSITY_LEVEL>

ex: make simulate test=apb_32b_write_test.sv uvm_verbosity=UVM_HIGH

# Note: You can find all the test case names in the path given below   
apb_avip/src/hvl_top/testlists/apb_regression.list

# Wavefrom:  
vsim -view <test_name>/waveform.wlf &

ex: vsim -view apb_32b_write_test/waveform.wlf &

# Regression:
make regression testlist_name=<regression_testlist_name.list>
ex: make regression testlist_name=apb_regression.list.list

# Coverage: 
 ## Individual test:
