I am working on the file "PYNQLearn/FabricOnly/.ipynb_checkpoints/myHDL_PYNQZ12_FabricOnly-checkpoint.ipynb".
The first task is:
myHDL Testing
Can you write Python program for it?
 What is a the Python program you requested?

#Here is the Python program you requested.

Peeker.clear()
clk=Signal(bool(0)); Peeker(clk, 'clk')
led=Signal(intbv(0)[4:]); Peeker(led, 'led')

DUT=BDCLed(clk, led)
    
def BDCLed_TB():
    
    @always(delay(1))
    def ClkGen():
        clk.next=not clk
        
    @instance
    def stimules():
        i=0
        while True:
            if i==1000:
                raise StopSimulation()
            i+=1
            yield clk.posedge
    
    return instances()
            
sim=Simulation(DUT, BDCLed_TB(), *Peeker.instances()).run()

Peeker.to_wavedrom()

BDCLedData=Peeker.to_dataframe()
BDCLedData=BDCLedData[BDCLedData['clk']==1]
BDCLedData.plot(y='led');
