Include a picture of your Digital circuit here:
Please comment on the single biggest issue you were facing when designing the circuit.
This was a relatively easy, so I didn’t face any issues.
Task 2-2: Build a 4-Bit 2:1 Multiplexer
Include a picture of your Digital circuit here:
Please comment on the single biggest issue you were facing when designing the circuit.
Version 1.1 Spring 2024 1
I didn’t face any issues.
Include a picture of your simulation (timing diagram) here:
Which tests did you perform and why? Use the following table to describe your test sequence. You need
to make sure to perform a suf cient number of tests to check the circuit for eventual faults.Ï
Test Stimulus Test Motivation Pass/Fail
2_0_2_1 Y should equal to a when sel=0 Pass
1_1_2_1 Y should equal to a when sel=1 Pass
