 For Realising EXOR gate how many NAND gates are required
 The time required for the data to setting, before the triggering edge of the clock.
Ans. Setup Time.  How can we change DFF to TFF
 How can we change SRFF to JKFF
 Minimum Number of 2:1 MUX required for 16:1 MUX

Hi..
I recently got placed through campus selections into Wipro VLSI.. But in the following offer letter that i got,it did not mention anything about VLSI.. Also offer letter looked same as that given to those placed in normal IT dept..
I am having this doubt whether they will put me back into IT field due to lack of any written records other than their verbal confirmation.
I would be very glad if you could tell me whether this is normal..please reply ASAP

Hi,
I recently attended an offcampus drive held for Wipro VLSI n managed til the HR round. I was told to wait for a week for the results. But till nw there have been no news of it. Are there any chances of not getting in even after HR round. Waiting for reply. Reply ASAP.
