It is you rx design front end that receives data, processes it and decides that it is now "locked" This may involve many complex modules if you are talking about say Thank you very much for you help. check over here
Why is the size of my email so much bigger than the size of its attached files? Check that the physical library actually has the packages dumped. Does DFT produces the same output as FFT? Moving the "000" outside of the type conversion also works ("000" & signed(...)).

Not the answer you're looking for? Since tx is sending data in a cyclic way then you can sync your rx prbs to beginning of any cycle once ready. Type std_logic_vector is not an array of bit. ** Error: D:/Quartus_code/ExModelSim/HW2/step.vhd(25): Type error in bit string literal. And avoid bit types unless you have really good reasons to use them - they don't mix well the std_logic; –Martin Thompson Dec 3 '09 at 17:10 add a comment| up
But internally, use the type that matches what your data is (so use integers, unsigned vectors, custom types, records, the works) Don't try and force everything into a std_logic type. Vhdl Conditional Assignment This means that you are using all of the std_logic_1164 package.

Thank you very much. So there will be delay. When you write code, you generally want to store your signals in either std_logic or std_logic_vector. Please tell me how? :( vhdl share|improve this question edited Dec 2 '09 at 17:13 Brian Carlton 3,86842343 asked Dec 1 '09 at 13:52 Bojack 86641732 add a comment| 2 Answers
