Description. * To illustrate a design flow for logic chips using Y-chart. Lambda Rules: This specifies the layout constraints in terms of a single parameter () and thus allows linear and proportional scaling of all geometrical constraints.Example:- Minimum Poly width: 4. Complementary MOS or CMOS need both the n-channel and p-channel MOS FETs to be fabricated in the same substrate. Clarification: Lambda rules gives scalable design rules and micron rules gives absolute dimensions. While at Xerox PARC, Ms. Conway also invented an internet-based infrastructure and protocols for efficient, rapid prototyping of large numbers of VLSI . Design and explain the layout diagram of a 5-input CMOS OR gate using lambda-based design rules. The proposed approach gives high accuracy of over 99.93% and saves useful processing time due to the multi-pronged classification strategy and using the lambda architecture.
