Testbench Environment

The TbEnv class (aliased as Tb) is the standardized testbench wrapper for all RouteRTL cocotb tests. It manages clock generation, reset sequencing, structured logging, and protocol monitor lifecycle.

Usage

from routertl.sim import Tb

@cocotb.test()
async def my_test(dut):
    tb = Tb(dut, clk="CLK", rst="RST", period_ns=10)
    await tb.start_clock()
    await tb.reset()

    # Attach protocol monitors (optional)
    tb.attach_monitors(axi_lite={"S_AXI": {}})

    # ... test logic ...

    # Assert no protocol violations
    tb.check_monitors()
