You said the assignment was 'I have to write behavioral vhdl code for a 4-bit register with parallel load, using a D-Flip Flop. Here is the D-FF code i have to use' Your bitreg42 doesn't use the dff code that you said you had to use. Noble accordion models.

Johnson Counter A Johnson counter is an n-bit shift register with the complement of the serial output fed back into the serial input. Johnson counter has 2n states. The keys to modeling a Johnson counter are: If most significant bit of the counter is a 1, then a 0 has to be shifted in from the right. . If most significant bit of the counter is a 0, then a 1 has to be shifted in from the right In-Lab: 1. Write a behavioral Verilog module for a 4-bit Johnson counter that has 8 states. The counter loads the '0000' state if reset is low. The counter should start and end with this state. Write a testbench to verify the correctness of the 4-bit Johnson counter. The testbench should have a clock with a period of 20ns and a reset signal. The testbench should store the 4-bit binary outputs of the counter in a file, which will be used to provide an input data stream for the sequence detector. 2. pr F pFY OFF SI ooo S3lo
Get more help from Cheggthis is my verilog code for a sequential add / shift multiplier. I am receiving 'XXXXXXX' as an output, if I set reset to high, I receive all zeroes as an output. Can someone please help me identify what I am doing wrong? Thank you for any tips/hints. Here is my testbench: any tips on how to write a better one would be great also.

2 AnswersAs Ciano pointed out, you are not kickstarting the clock correctly. Tropico 6 crack free. Also you never assert reset in the TB.

The following should help you test your module. But it seems like your module doesnt work.
