Try to move part of the code into a concurent statement. Something like this:
assign aux = frame_line_size - (player_1_length << 1);
And then rewrite your code as:
if((controller_buffer[RIGHTPAD]) && (player_1_pos < aux)) begin
player_1_pos = player_1_pos + 1;
end

Naa, it doesn't seem to work. Thanks anyways.

Obviously. The design is effectively not synthesizable, because the complexity of set_pixel actions exceeds the logic resources of any available FPGA. It doesn't work this way.

I think this is my problem. I guess I'll have to spread the work across several clock cycles. But, the odd thing is that when I replace this code that just increments/decrements based on a buffer flag:
if((controller_buffer[LEFTPAD]) && (player_1_pos > 0)) begin
player_1_pos <= player_1_pos - 1;
end
if((controller_buffer[RIGHTPAD]) && (player_1_pos < (frame_line_size - (player_1_length * 2)))) begin
player_1_pos <= player_1_pos + 1;
end
with something like this that does a lot more processing:
draw_player_1(player_1_pos, player_1_y + 20, GREEN);
it compiles in 3 minutes, while the former code eventually runs out of memory after an hour. I guess the compiler is doing a lot more background work on the first block of code than the second block of code that I am not aware of.
Thanks for your response.
