![]() ![]() If rising_edge(sampleCLKreqINDV) then -100MHz Clock. OVERSAMPLE_DATA1: process(sampleCLKreqIN0, ImodDATA, QmodDATA) The problem here is that dataOUT is multisourced :( The flip flop is used to store data and for shifting purpose. The main objective is to convert 3- bit parallel input data into serial output data. Should I instead use a sample clock twice the frequency and just trigger at the rising edge when implementing the shift register or can i still trigger at the falling edge. Abstract -This report enumerates the analysis and design of a circuit containing D-Flip Flops to form 3 - Bit Parallel Input Serial Output Shift Register using NGSPICE software. i have two signals (ImodDATA and QmodDATA) 11-bits wide that are concatinated with 3 more bits to yield the desired 14-bit dataOUT output. Any help would be greatly appreciated.ītw, sampleCLKreqINDV is a sampling clock of the ImodDATA and QmodDATA. Im attempting a parallel to serial conversion but im having difficulties implementing it. Now, I assume this can be done with shift registers and maybe using an inout temp signal but I am uncertain as how to proceed. there are some conditions as described in the code, but the problem is that I want QmodDATA to follow ImodDATA hence the parallel to serial conversion.
