Warm-up Problems

• Adder/subtracter from last lecture.
• RC Circuit.

Things we didn't get to last lecture

• Examples of VLSI Layouts at different levels (textbook, ...
• CPU Info Center, a gold mine of information on current CPU chips from Intel, Motorola, IBM, Digital, ARM, TI, etc.

• Analysis Tools

Coming up in next lecture

• CMOS Process and Layout
• Here is a link for the MOSIS service that provides fabrication services for universities like us. You can find out about design rules, tools and fabrication issues.
