Well, let’s start with the#1assignment delay. In this case, it’s not representing a true hardware delay. No, the#1is there in order toscheduleVerilog simulation statement execution. Part of the reason why it’s there is because the rest of the block usesblockinglogic (i.e. via the=)...
You have a Verilog simulation race condition in your code. You are trying to assign y to the value of a at the time a changes at time 35ns. The simulator is not guaranteed to assign 0 or 1 to y. It can choose either value and be compliant with the IEEE Std 1800-2023. The simula...

Normally you would ensure that lwe is assigned in all cases of your if statement to avoid inferring a latch, however this appears to be your intention in this case. Latches in general should be avoided, so if you find yourself needing one you should perhaps pause and consider your approach...
