 ### Recirculation MUX RTL implementation
 
 - solution for data bus synchronization
 - uses a toggle pulse synchronizer to transmit a pulse across clock domains
 - pulses controls the sampling of the data bus on the receiving (sink) domain
-- CoCoTB testbench for functional verification
-    - $ make
-- CoCoTB-test unit testing to exercise the CoCoTB tests across a range of values for the generic parameters
-    - $  SIM=ghdl pytest -n auto -o log_cli=True --junitxml=test-results.xml --cocotbxml=test-cocotb.xml
