VLSI and VHDL is digital simulation. That's not a chip design course.

Actualy Chip design courses are:

Analog and mixed signal IC decigns-ADC DAC, PLL, Comparator, switched Cap, OpAmps, Current Mirros etc...

You have to know ORCAD, Mentor Grpaphics, LEDT to design actual chip...

VHDL AND VLSI is completely different side....
