dear all,
i want to concatenate a register(of dynamic size as for concatenation) 
with n no:of zeros where n is a  generic integer number.please help!!!
Thanks in advance....

dear all,
i want to concatenate a register(of dynamic size as for concatenation) 
with n no:of zeros where n is a  generic integer number.

say for eg
num1_reg := "00" & num1;--here only two zeros are only used

i would like to make it something that would work like this

 num1_reg := "N zeros" & num1;--wherein n is a generic number

how to make it work..please advice...
thanks in advance

num1_reg := (n-1 downto 0 => '0')  & num1;

But you don't need a generic

num1_reg := (num1_reg'high downto num1'length => '0') & num1;

does the same.

i don know what this statement does!!

num1_reg'high downto num1'length => '0' ??

num1_reg'high ??

num1_reg'length ??

thanks bko, got sorted it out...
