Experiences on VHDL based methodologies on industrial ASIC design

Abstract

This paper presents the design of two ASICs (CIMCO, PEC31750), both implemented following a VHDL based top-down methodology. CIMCO is an adaptive equaliser based on a Decision Feedback Equaliser (DFE) which is intended to be included in a cellular phone improving the demodulation stage in a DECT path. PEC31750 is a radiation hardened peripheral controller for embedded space applications. This chip is designed to work with the MA31750 processor, and both chips together form a general-purpose microcontroller system core for embedded space applications on-board spacecraft.
