The objective is to design a complete mixed-signal IC from system specification to a final
design layout as required for submission to an IC foundry for fabrication
Topic: project must be specified for a specific application requiring analog I/O (sensing & outputs)
with on-chip analog and digital components (data converters, amplifiers, digital logic). One
example is a controller for a specific plant (e.g. power converter) requiring sensing of
various signals, feedback compensation, and output drive.
Scope: you are to design the complete IC, including full layout with PADS, and provide simulation
results demonstrating operation in the application. Circuit behavior of the system outside of
the IC can be implemented using functional (verilog, verilog-A) and / or circuit blocks.
Core blocks: your project IC must include analog and digital blocks. You are welcome to reuse blocks developed in the homework assignments.
Final design includes matching top level schematic and layout views with pads that are
design rule check (DRC) and layout-vs-schematic (LVS) clean
All students are to perform projects in groups of 1 to 3
The project is graded based on three in-class project reviews and a final report.
Detailed circuit design and simulations for individual blocks completed to date
Complete I/O description and layout area estimation for IC
PAD cell selection for all I/O
Layout of padframe based on estimated area and PAD cells
Package selection and bonding diagram based on initial padframe
Project Review #3: Final review (in-class presentation)
Complete circuit level simulations of the top level IC
Full design, layout and verification of individual IC blocks
Final project report
The final project report must include the following sections:
General Overview: marketing level highlight of IC, key features
System Description: block diagrams & (brief) description of using your IC in a complete system,
table of pin-out, pin descriptions, allowable pin operating voltage or current ranges
General IC Operation: block diagrams & description of internal IC operation
Implementation Details: description & operation on each sub-block
Verification: full DRC and LVS results, simulation results for sub-blocks and top level IC
Schematics: attach schematics of the complete design and sub-blocks and verilog code
Package: details on selected package and bonding diagram
Testing Plan: describe a testing plan that could be performed at the IC packaging house for functional
verification of the IC, including required equipment, testing configuration, procedures, and
specifications. Testing Plan Example.
