First verilog project

The accumulate and average codes do not work. Maybe you can run simulation to understand better.

When the same node is updated multiple times in LHS of non-blocking assignments, only the last one takes effect.

In the code, IEtotal gets reduced to effectively single statement of "IEtotal <= IEtotal + Iearly[4095];". IEtotal is always X without reset. Similarly for the other regs in the loop.

For summation of IEtotal, you can create intermediate combinatorial adder before feeding it to IEtotal. Break it into 2 "always" blocks. Something like,

always @(posedge sysclk)

begin

...

IEtotal <= IEtotal_intermediate;

...

end

always @*

begin

IEtotal_intermediate = 32'h00000000;

for(n = 0; n < 4096; n = n +1)

IEtotal_intermediate = IEtotal_intermediate + {31'h00000000, Iearly[n]};

end
