Should you remove all warnings in your Verilog or VHDL design? Why or why not?

In (regular) software I have worked at companies where the gcc option -Wall is used to show all warnings. Then they need to be dealt with. With non-trivial FPGA/ASIC design in Verilog or VHDL there are often many many warnings. Should I worry about all of them? Do you have any specific techniques to suggest? My flow is mainly for FPGAs (Altera and Xilinx in particular), but I assume the same rules would apply to ASIC design, possibly more so due to the inability to change the design after it is built.

Verilog code simulates but does not run as predicted on FPGA

I did a behavioral simulation of my code, and it works perfectly. The results are as predicted. When I synthesize my code and upload it to a spartan 3e FPGA and try to analyze using chipscope, the results are not even close to what I would have expected. What have I done incorrectly? http://pastebin… >>> More

VHDL, using arithmetic & variables in "downto"?

Hey, Quick VHDL question, I don't have access to Xilinx at the moment due to dead laptop, so can't test this. I was wondering if it's possible to use variables and arithmetic in 'downto' statements, e.g: proc: process (x) begin y <= z(x downto 0) & z(7 downto x); end process; Thanks. >>> More
