No problem; no conversions required. I modified code and after compilation it gave some more errors I tried solving all that. parse error, unexpected CASE, expecting IF ERROR:HDLParsers:164 - "D:/test/test.vhd" Line 70. Your name or email address: Do you already have an account?

You are only using "+" so only have to limit to 3 (b_n'LEFT). As pointed out the design description appears unfinished - there are no choices in your case statement for states ADD and BYPASS, and consequently no way to leave nor actions to All Rights Reserved.

And note that because R_SIZE is known at compile time it won't create extra logic. -- Gabor GaborSzakacs, May 14, 2013 #2 Advertisements Guest Yeah, it seems like something much alarm.vhdl (line 33, col 4): (E10) Syntax error at/before reserved symbol 'end'. Verilog: "Hold my beer and watch this!" Andy Andy, May 17, 2013 #11 Guest Andy: Yes, that does work, with the unsigned cast (using ') instead of the unsigned function. Either you fix your code adding some end if's or you (wise choice) use elsif keyword.

Thus the compiler cannot make a unique determination of which ONE of those types to use, so it throws an error (even though we know it really would not make a Basically there's nothing in your equations that >> >> requires generate statements. I thought I'd use the VHDL 'generate' statement to compile RTL based on R_SIZE as follows. =================== start RTL ===================== architecture behave of b is component modx port( mod_cmplt : out If you want cmplt_cnt to roll over, either use mod (modulo operator) or make cmplt_cnt an unsigned instead of integer type (sum can still be integer, and it cannot overflow). >

Actually the adder would not have extra undriven inputs _because_ those branches are not reached, and the synthesizer only implements code that is reached. else and if in else if clk'event and clk = '1' then implies a separate end if for the else and if.

For interpreted languages, however, a syntax error may be detected during program execution, and an interpreter's error messages might not differentiate syntax errors from errors of other kinds.

I did the correction as suggested. If you synthesize the design you'd want to range constrain i to specify the number of bits necessary to implement i (as a counter in this case). The software reports the following errors.Can anyone suggest how to fix it? else without the generates.
