Sobald ich den offset in Zeile 127 auf =63 abfrage kommt folgender Fehler ERROR:Xst:1534 - Sequential logic for node appears to be controlled by multiple clocks. I used xc9535xl to generate gate time using a 10MHz clock and its work fine. mean? I try to describe a driver bloc of BRAM.

Example: Let's assume there is a Nios running on a FPGA that sends randomly (or every second) a string to an attached display over the SPI interface. I am at a point where I can understand & appreciatewhat you have done... The underlying architecture is based on D-type latches, and they only have one clock input. learn more… | top users | synonyms 1 vote 3answers 523 views Using BUFG to drive clock loads I'm attempting to work with pixel data that is output to a DVI

The logic you need is something along the lines of this (grossly oversimplified to highlight the important point):Code: [Select]IF rising_edge (clk) THEN
cnt <= cnt + 1;

IF rising_edge (snapshot_signal) THEN
Looks like this is a limitation of the CPLD and the ISE synthesis tool is too dumb to solve it. Ten en cuenta que sólo puedes ver los posts escritos en zonas a las que tienes acceso en este momento.

I know the bp := bp(0 to 6) & '0'; statement, but I still wanna use this sll. Est ce que quelqu'un pourrait m'expliquer mon erreur , je comprends pas pourquoi on ne peut pas faire ca. I'm trying to make a counter with a sensor, the counter will be in the FPGA to show on a 7 segments, the code does not show error but when I Sieh dir doch mal an, wie andere einen getakteten Prozess beschreiben (und vor allem, wieviele Takte in einem solchen Prozess auftauchen).

Il se trouve que j'essaye de coder l'algorithme de Montgomery en VHDL, et que je butte sur un petit problme : voici mon code : process(A,B,M) variable q,s_int,s_intold,expr1,expr2 : std_logic_vector(N-1 downto Im Selben Code kommt die Meldung: WARNING:Xst:1989 - Unit : instances , of unit are equivalent, second instance is removed In RTL Schematic sind jedoch mehrere PWM enthalten, was I am at a point where I can understand & appreciatewhat you have done... Y a du mail avant de pouvoir faire du code niveau DO254!

Nach meinem verständniss müsste dann doch da eine Fehlermelduing kommen, weil offset nur bis 63 geht. In Zeile 127 frage ich einen integer ab, den ich in Zeile 76 mit signal offset : integer range 0 to 63; definiert habe. Il est actuellement 04h31. clever.I'm sure you know this but for others here is a binary to gray conversion formula: gray = (bin >>1) ^ bin Logged FrankBuss Supporter Posts: 1032 Country: Re:

None do.What you need to do, therefore, is have two registers. Cependant cette solution ne peut me convenir car il faudrait par la suite que je mette jour s_intold car je suis dans une boucle : s_intold <= s_int; et la I used Uc for displaying and user interface.One more dought , wheather an input clk is needed to CPLD to work or not. ISE 14.7 at synthesis returns the following warning on the subsequent line which eventually leads to an error: "Width mismatch. has a width of 8 bits but assigned expression is
