AWR published a new application note. The article explains how to complement Microwave Office circuit design software with National Instrument’s Multisim circuit simulation software and Ultiboard printed circuit board (PCB) layout software for a comprehensive design flow spanning from DC to microwave frequencies. The title of the technical paper is Multisim/Ultiboard for Low-Frequency Simulation and Layout.
AWR published a white paper about correctly predicting cellular, radar, or satellite RF link performance early in the design cycle. The article highlights the advantages of using Visual System Simulator (VSS) RF system simulation software for detailed insight into the full performance of an RF link in next-generation wireless products. The title of the technical paper is: Understanding and Correctly Predicting Critical Metrics for Wireless RF Links.
ASSET InterTech has published an introductory tutorial on IJTAG. The tutorial explains how the new IEEE P1687 Internal JTAG (IJTAG) standard simplifies and automates the way chip designers manage embedded instruments that perform chip validation and characterization. The article describes the on-chip IJTAG architecture and the two languages defined by the standard, Instrument Connectivity Language (ICL) and Procedural Description Language (PDL). ICL defines the connections among embedded on-chip instruments and PDL is an extension of the Tcl (Tool Command Language) for developing validation, test and debug vectors for execution by IJTAG instruments.
Vincotech has published an article titled, Mastering Power Modules: The advantages over discrete solutions. According to Vincotech, power modules have become the most convenient way of building a cost effective power supply system. Everything is optimized within the constraints of the particular module manufacturer. The designer can rest assured that the module will do everything electrically and mechanically that is specified, is guaranteed to work to tight specifications such as EMI, efficiency, load cycling and reliability and it is virtually off-the-shelf meaning that the all-important time to market pressure is minimized.
