    combo logic /latch inference

    hi it will infer flops only but that is bad coding style. use non blocking statements and u can change order of those assignments if u want to use blocking then u have to aware of sequence of the assignments to be write

    19 input XOR gate with 2 input XOR

    hi u can implement in two ways 1. in first stage 2 inputs are given as input the left out input will be added to 2nd stage like that u can draw until u reach to the end with single output. 2. apply first two inputs to first xor gate out put of this gate is combined with new input for next...

    question on a shadow waveform?

    it specifies according to the application When u r dealing with different speed devices, that signal will be asserted from first line to last line depends on device for faster devices, the signal will change quickly for slow devices, the signal will change late so it is like range to get...

    What exactly is the Verification IP?

    Re: Verification IP To provide testing block inside the design along with the DUT which is called built-in-self test while power on the system this checks the entire system

    Software used for simulation of basic VHDL

    Re: about VHDL... many vendors provide simulators for simulating HDL designs modelsim by mentor graphics ISE by Xilinx ncsim by CADENCE i am not aware of free simulators which works for all designs

    The diffences between unsigned.all, numeric.all and arith.all (VHDL)

    Re: vhdl packages If the operands of STD_LOGIC type, one has to use .arith package which is provided by IEEE to perform any arithmetic operations ( In the package they defined resolve when the operands taking other than '0' and '1') Eg if X = z; Y = x; then if RESULT = X * Y; then what will u...

    How long will it take to shift an 8-bit number into 8-bit serial in, parallel out?

    Re: register question For SIPO it takes 8 Clk pulses For SISO it takes 15 Clk pulses For PISO it takes 8 Clk pulses For PIPO it takes 1 Clk pulses

    TWO"S complement

    For finding 2's compliment first search for '1' from LSB and put upto that position as it is and the remaining bits ( upto MSB ) compliment the bit. for searching '1' frm LSB we can use priority Encoder by prioritizing LSB as highest priority

    Blocking and Non-Blocking assignment

    blocking and non-blocking in vhdl Both statement blocks are correct. But using non blocing stmt assignment is good practice and using blocking stmt is bad coding style

    validation of a project means what ?

    Validation is checking the design after it exists physically ( checking functionality of IC) . verification is done after coding
