Hello Murali

Old IITs are good. I will write as per the preference given:

IISC CEDT

IIT D - IEC AND VDTT

IIT B - ES AND MICRO

IIT M - BEST FOR ANALOG ( REALLY INTERESTED ANALOG GUYS SHOULD OPT FOR DIRECT PHD OR MS)

As fas as new IIT's are concerned, last to last year IIIH discontinued the VLSi course same with IIT mandi.

So, if you can get new IIT's then please opt for the best NIT's for VLSI other than new IIT's.
