Signal has multiple drivers

Signal has multiple drivers - vhdl

Error appears in translate phase that signal clkin2 has multiple drivers although it doesnt , main clock signal enters a DCM which generates 2 clock singles 1 acts as a clock for my vhdl module and other act as a clock for microblaze , the clkin2 is the clock of microblaze and its telling me it has multiple drivers ..
here is the code for my top vhdl :

Thanks in advance

If fpga_0_clk_1_sys_clk_p_pin and fpga_0_clk_1_sys_clk_n_pin are signals of a differential clock, you should instantiate a IBUFGDS or something like that (check the clocking resources manual of your FPGA family for details)

Thanks to the idea of baldyhdl the problem was entering to the micro blaze a clock signal from PLL and another one directly from N pin of the differential clock , correct solution was to change micro blaze clock from differential clock to single ended and use differential clock to produce 2 clocks , one for microblaze while other for the rest of the design,
Thanks for the help

HDMI Pass Through with RGB Switch Filter

I'm very new to VHDL and FPGAs, and have hit a rock. Im currently working on video filters on the zybo z7-10, and started off using this guide to create a HDMI passthrough on the board:
https://github.com/dpaul24/hdmi_pass_through_ZyboZ7-10?_ga=2.34188391.796043983.1579510279-2100398226.1578999679
So after getting that working all i want to do is be able to effect the video output. To do this, I tried to set the rgb 24 bit vectors last 8 bits to 0, removing all blue from the output. If i try the following code (with or without the process block) i get a syntax error on the "if" statement line
process is
begin
if sw ='0' then
vid_pData(7 downto 0) <= sw
end if;
end process;
The issue is I don't seem to be able to put this anywhere in the code without causing an error. Can someone explain what's happening here?

EDIT: changed my if statement to
vid_pData(7 downto 0) <= "00000000" when sw = '0';
and it got rid of the error but the implementation failed. The failure is:
[DRC MDRV-1] Multiple Driver Nets: Net
dvi2rgb_inst/U0/GenerateBUFG.ResyncToBUFG_X/vid_pData[0] has multiple
drivers: vid_pData_reg[0]/Q, and
dvi2rgb_inst/U0/GenerateBUFG.ResyncToBUFG_X/poData_reg[0]/Q.

You're not writing software, you're designing hardware. Your extra code drives signal vid_pData. So, does component dvi2rgb_0. So you have two drivers on that signal. A short circuit in other words.
Also, you do not say what value vid_pData should take if sw is not equal to '0'. Therefore, you will get latches in your hardware. (Google "inferring a latch".)
You need a new signal, eg:
signal vid_pData_new : std_logic_vector(23 downto 0);
then you need to assign a value for both sw equals '0' and '1', otherwise you will get a latch:
vid_pData_new(7 downto 0) <= vid_pData(23 downto 8) & "00000000" when sw = '0' else vid_pData;
The & operator is the concatenation operator. Finally, you need to drive component rgb2dvi_0 with your new signal:
rgb2dvi_inst : rgb2dvi_0
port map (
TMDS_Clk_p => tmds_tx_clk_p_o,
TMDS_Clk_n => tmds_tx_clk_n_o,
TMDS_Data_p => tmds_tx_data_p_o,
TMDS_Data_n => tmds_tx_data_n_o,
aRst => async_reset_i,
vid_pData => vid_pData_new, -- <-----------------
vid_pVDE => vid_pVDE,
vid_pHSync => vid_pHSync,
vid_pVSync => vid_pVSync,
PixelClk => pixelclk
);
Can you see what has been done here? We have inserted a new piece of hardware that drives the new signal vid_pData_new and have specified its value for both possible values of sw. We must do this, otherwise we will get latches. We are designing hardware, not writing software.

Connect carry out to carry in for adder/subtractor in structural VHDL

So I have the following VHDL code to implement an Nbit adder/subtractor using only a 2:1 mux, an inverter (flips bit), and a full adder. I am having issues connecting the carry out of an adder to the next ones carry in while having the first adder have a carry in of i_Control. Any help would be greatly appreciated :).

end generate;
end structure;

Make the carry array one longer:
signal carry : std_logic_vector(N downto 0); -- was N-1
and change this:
o_Couts => carry(i));
to this:
o_Couts => carry(i+1));
in your generate statement while leaving the i_Cin carry input association as is.
If the last carry out isn't conveyed through an output port the net will get eaten during synthesis.

Problems with .ucf file for my microblaze system in ISE

ok so i added my microblaze from XPS generated a topvhdl file added the ucf file and in my microblaze i have 4 GPIO but i didnt put any of thier pins in the .ucf file although they are present as inout in the topvhdl but i was able to compile the project and gnerate a bitstream.
Now i commented out all the GPIO Pins in top vhdl and connected my microblaze system GPIO with internal signals as shown This also didnt case any trouble and i could generetate a bitstream.
Now what caused the problem is when i added the 7 ports of LED to external pins of my top vhdl file( which has nothing to do with my GPIO) it started telling me errors on the GPIO pins!!! here is the code :

this is a comment, because i am not yet allowed to make comments :/
I am not sure, if the error is a failure. I would rather say that not not print an error message before is a failure. If you are handling some inputs, you should be always aware of shortcuts. Try to set those as open, so they aren't connected at all to your FPGA.

vhdl code wrapper

I'm trying to implement a VHDL project but I'm having problems connecting the different components correctly. I just want to make sure that I did this correctly. The code below is just the wrapper (which, to this point, is where the problem lies). Please let me know if I'm connecting the input and outputs to each component correctly.

Signal has multiple drivers - vhdl

If fpga_0_clk_1_sys_clk_p_pin and fpga_0_clk_1_sys_clk_n_pin are signals of a differential clock, you should instantiate a IBUFGDS or something like that (check the clocking resources manual of your FPGA family for details)
