This is a code and simulated waveform of booth multiplier when we simulated it on xilinx9.2i, the syntex is cheked but on generating the waveform we are not getting the correct output instead of multiplication, waveform shows the previous value of input. please check the code and reply the correct code on my email id-anchalagarwal92@gmail.com

See the error message? Do you understand the error message? Whats the value of uninitialized std_logic_vectors? Try to initialize your signals like that: signal sum, dif: std_logic_vector(mc'RANGE) := (others=>'0'); BTW: forget about that old obsolete libs use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; and the stupid calculating with vectors. Take the use IEEE.NUMERIC_STD.ALL; instead!!!

However some improvements in your question could change this: 1. give at least a small explanation of what the code shall do! You want our help, so give some information first. 2. start an own thread for your problem, this one is over one year old! (and I assume from your name, that you are not the original author) 3. don't give your code as .prj-file. I assume from the file name that your code is written in VHDL so use the VHDL-type file ending (.vhd or .vhdl) for proper syntax highlighting! Thanks.

I'm very sure that thats no kind of "code". > please find the error in my code Pls start a NEW thread, when you have a NEW question. And there you can describe WHAT the "code" is expected to do. And WHAT ist actually does instead. And HOW you did find that out. And if there are any errors reported from your toolcahin you can write WHAT errrors from WHAT part of WHAT toolchain. And before sending your post you can read it as if you were somwhere on the other half of the earth and you don't know anything about your problem. And if you find, there's enough information, then you may press the "SUBMIT" button.
