I recently starting prototyping my hardware design using Modelsim Altera edition. I am struggling to figure out what is going wrong with some of my sequential hardware (Its an ALU). The ALU instruction and data are only sent during one clock cycle however the output makes it look like it was sent for more then one. I am confused to why it is generating this output as it is just sequential hardware. You can see the results below. The ALUinstruction is at the bottom and the ALU output is at the top. I did not show the other inputs, HOWEVER I have already know that they only last for one clock cycle.

EDIT: Reinitializing did not fix it
