you need to define the component just to give the ports of the particular module you will be using in that program.
the smaller blocks grow up into bigger blocks
you need to define the ports of the smaller blocks for the bigger block similarly like netlist in tanner eda software
See i have worked upon flash adc
i have worked in 10MHz range
but i have worked in 3bit adc resolution, higher than that is difficult to perform using flash adc
pipelined is a stack of flash adc its bulkier than flash and so is delta sigma i believe
but it is true that the resolution in...
can't tell about DAC but there are many types of ADCs
each and every one has its advantages and dis advantages
it depends on you which type of adc will you be doing
i can provide you flash adc architecture only...............i have worked on it
a problem occurs when i code 2bit flash adc using the 3bit flash adc code
the pattern of the output waveform changes completely
but i can't find the difference between the two codes
after all i have made the 2bit out of the 3bit by removing some coding lines that's it
but the waveform pattern...
when i create a 2bit flash adc using schematics in tanner tools its power comes as 70mw but when i create the same circuit using sub circuit in tanner tools netlist the power comes as 77mw
why does the power increases using sub circuit???
i have created a 3 bit flash adc in tanner eda software
but so far from all the information i have got from net
there's a contrast in the wave pattern
i have managed to create both of the type
but i don't know which one is correct and why
i am giving both the waveform diagrams
please check and...
no he hasn't mentioned the multiplexer32to8 code here
he has just mentioned the component
thanks vipinlal for the black box concept
and hyro i would suggest you to code simply
AOut <= OutA_temp;
BOut <= OutB_temp;
COut <= OutC_temp;
DOut <= OutD_temp;
EOut <= OutE_temp;
your code does give a output
but i don't think that is what you want
if you are doing this coding in xilinx then try to correct the warnings
your code has 56 warnings
and by the way can anyone tell me what is a ' black box module' ??
your code warning shows all the port map connections as '...
see i know this condition
i told you before also
i need all the 8 input conditions '000' up to '111'
my encoder has 7 input terminals and also shows 7 high low conditions but i need to have 8 high low conditions using cmos technology
your given circuit seems to be made through vldl programing...
