SOC designs are major, high-risk projects and most consist of many IP blocks — some developed in house and some purchased. Many of the most complex blocks are processors and DSPs. With their associated software-development tools, simulation models, and EDA flow scripts, these processor IP blocks affect more than just the hardware design; their influence permeates the entire SOC design project. Consequently, processor IP can literally make or break your project. Here is a list of questions to ask yourself, your team, and any processor IP providers you contact. This list will help you to avoid unhappy IP choices and will help you get exactly what your team needs to develop successful SOC designs on time, within budget, and with minimal hassle.
