VLSI(Very large scale Integration) domain is a very-vast field which requires expertise in multiple domains with lots and lots of challenges built-in to meet today's requirements .
A good VLSI designer is one who should have both length and breadth of knowledge to understand and appreciate the complexity and knowledge enough to take decisions with various trade-offs in the design phase.
To achieve this the Chip Designer requires , knowledge of various protocols, architectures, models, formats, standards, knowledge about CMOS logic, Digital Design concepts, taming the EDA tool for the various design requirement's like area, timing, power, thermal, noise, routability, lithography aware, knowledge about Various variabilities like channel length, Vt, line width variations, lens abrreations, IR drop effects,inter-die, intra die-variations, effects, and various noise-effects like Package noise,EMI noise,power grid noise,cross-talk noise and ability to test and validate and know to model and characterize all these effects upfront in the design-phase,steps to increase yield to increase profitability curve, with short span of time-to market to minimize the risk and maximize the predictability and an modular approach to Success. Now let's dwelve in to the "Art of Designing"
I had used lot of Technical Jargons, nothing to worry about we will get in there soon...
Before Designing a Chip? Need to ask few questions ourselves.
1. What market the Chip is targetted for?
2. What are the Protocols involved in the Chip?
3. What is going to be our Processor/Bus Architecutes?
4. what is the power/IR-drop/timing/Area/Yield/ targets and how to budget it in the Chip?
5. What is the process in which the Chip going to be manufactured?
7. what are the various third party IP's/Memory requirements?
8. what is our Design flow and EDA tools and methodology involved?
9. What is the estimated Chip Cost?
10. What will be our Profit model ,estimation of our ROI(Return of investment)

The best contacts and resources to help you get it done
Complete Knowledge and Concepts of VLSI Chip Design
A website discusses about the Concepts behind Chip Designing and it is a free resource, dedicated to VLSI chip designer's community.
I recommend: www.vlsichipdesign.com , has the details about Chip desiging in a manner even a novice Engineer will appreciate and VLSI chip designer's can contribute contents to uplift their own community in the Knowledge front by sharing their design knowhow's and the experiences in their chip designing .
Very Large Scale Integration(VLSI)
VLSI , the process of creating integrated circuits by combining transistors in a chip.
I recommend: http://en.wikipedia.org/wiki/Very-large-scale_integration , explains what is VLSI ?
