Abstract
This paper presents a flexible and portable dig-
ital framework for Built-in Self-Test (BIST) and calibration of
RF/analog circuitry. Novel to the proposed testing framework, is
ar e u s a b l e ,flexible, drop-in IP core, composed of a centralized
custom processing engine with da ta path, memory architecture
and instruction set optimized for ef ficient execution of compute
intensive test and calibration algorithms. The innovative BIST
engine is complemented with a calibration and test sequencing
