Hello, I am attaching here a multi-stage cascode amplifier schematic operating at very high frequency at bw of 28GHz. A part I have understood about the circuit as following From RFin signal travels through L and C matching network then from source degenerated CS stage to cascode stage. The output from first stage is link with (...)
Removing a tmp signal can't resolve the issue. You need to reconsider the circuit. The p1_sum etc. signals can be only driven by one side, either as output of the summation block or in the process.
The following code results the error: Line 74. signal key_state has a multi-source. The code is written for a keypad scanner. I cannot make out why "key_state" turned out to be multi source signal. Please help!!!!!!!!!!!!!! -- Thanks in Advance! :) library ieee; use (...)
Hello All, Please look at the following code - I am geting these errors : Line 47: signal data_valid_demod in unit DeModulator(8) is connected to following multiple drivers: Line 45: Driver 0: output signal data_valid_demod of instance Flip-Flop Line 47: Driver 7: output signal data_valid_demod of instance (...)
You are connecting a single SCL signal to multiple instances. You'll get a multiple driver errors, if SCL is a bidirectional signal in the component. A pure input signal should'n give an error. We need to see the component definition to understand the problem.
Hi, I am using dual port ram as two single port ram of diiferent width, one with 11 & other with 9. this is required for designing nand flash memory controller.one port is used for sending 2048 bytes to nand flash and the other port for sending 512 bytes to ecc module to generate parity bits. i am getting these errors for dual port ram alone(not
Hi, I am implementing a verilog code for UART in my code but every time I synthesize it, I get the following error: ERROR:Xst:528 - multi-source in Unit on signal ; this signal is connected to multiple drivers. The code for UART is pretty lengthy and I think that the problem lies in (...)
I am getting the following error: ERROR:Xst:528 - multi-source in Unit on signal ; this signal is connected to multiple drivers. Drivers are: signal in Unit is assigned to GND So I have read that you cannot use the same variables in two (...)

Hi, multi source error occurs when you force a signal simultaneously in two processes. As the process runs parallely,signal will be confused which value to take. for ex: Process() begin a<=5; end process; second :process() begin a<=6; ....... ...... ..... end process; here signal a shows (...)
pls help me with this piece of code.... it's giving error like "multi-source in unit control_block on signal DCO_CONTRL&" how to fix this error..?? module control_block( reset, enable, ext_clk, clk2, fast, slow, up, dn, DCO_CONTRL, phase_acquisition_mode, pll_lock ); input reset, enable, ext_clk, clk2, fast, slow, up, dn; outpu
Your code has multiple outputs connected together. Probably two different statements simultaneously driving the same signal. If you need help locating the problem, show the HDL code.
Mutlicycle paths are signal paths that require more than one clock cycle to propagate. You specify to the STA tool how many clock cycles you want to allow the path to get from the source clock edge to the destination clock edge.
"WARNING:Xst:528 - multi-source in Unit on signal not replaced by logic." This warning often appears in conjunction with "Xst:529." Solution 1: This warning appears when XST determines that there is contention on a particular signal. If the processes assigning values to this signal (...)
i m trying to do a simple robot controller in verilog ..while trying to to synthesize my code its showing an error message like this........ ERROR:Xst:528 - multi-source in Unit on signal > ERROR:Xst:528 - multi-source in Unit on signal > (...)
Dear all, Could anyone teach me how could I measure the multi-path effect of my tested circuit? multi-path means the RF circuit receive more than 2 same signals in different path from a single transmitted signal source. Is there are any testing equipment could emulate this effect? Could you (...)
