Move TinyALU clock generation to cocotb testbench #2
Conversation
…0.1. Still hangs.
Modified `tinyalu.vhd` to remove the internal clock generation and expose the `clk` signal as an input port. This allows the clock to be driven by an external source. Updated the `TinyAluBfm` in `tinyalu_utils.py` to create and start a 2us clock using `cocotb.clock.Clock`. The clock is started in the `start_bfm` method, ensuring it is available for all tests that use the BFM. This change centralizes clock management in the test environment, removing the need for the DUT to generate its own clock and making the test setup more flexible and realistic.

Moves the clock generation for the TinyALU example from the HDL design into the Python-based `cocotb` test environment. The clock is now created and started as a coroutine from within the `TinyAluBfm.start_bfm` method. This change achieves the goal of centralizing clock control within the test environment for the Verilog version of the design. The VHDL implementation and its corresponding Makefile have been reverted to their original state. This is due to unresolved simulation timeouts and VPI interface errors when attempting to drive the clock from the testbench with GHDL. The Verilog implementation is fully functional with the new clocking scheme.

This refactoring moves the clock generation for the TinyALU example from the VHDL design to the
cocotbtestbench.Specifically, the changes are:
tinyalu.vhdhas been removed.clksignal intinyalu.vhdis now an input port.TinyAluBfmintinyalu_utils.pynow creates and starts a 2us clock on the DUT'sclkpin.This centralizes clock management within the test environment, making the setup more flexible and aligning with standard verification practices.
