Tahoe RF Semi has developed a rigorous design methodology that has proven valuable in consistently delivering first time silicon successes. It includes several decision checkpoints (DCPs). These checkpoints are designed to ensure that a project doesn't proceed to next phase without appropriate due diligence through design reviews. The main DCPs and the design reviews are:

DCP1 - Opportunity Assessment Review (OAR)
Is the project worth pursuing?

DCP2 - Concept Review (CR)
Is the design technically feasible?

DCP3 - System Review (SR), Interim Design Review (IDR)
Can the design proceed to the main design phase?

DCP4 - Critical Design Review (CDR), Test Readiness Review (TRR), Interim Layout Review (ILR)
Is the design in compliance with its objectives?

DCP5 - Final Design Review (FDR)
Is everything ready for tapeout/release?

DCP6 - Tapeout Review (TR) & Design Verification Review (DVR)
Is the data complete and ready for final release?
