Abstract :
Printed wiring board (PWB) thermal modeling tools developed at Texas Instruments are described. These general programs help automate the processes of: finite-difference-model generation for PWBs and other rectangular, layered structures; definition of heat inputs to a thermal model of a PWB due to electronic components; and calculation of component junction temperatures for devices located on a modeled PWB. The features of the programs are described and their usefulness in the design environment is explained. The direction of current and anticipated future development is addressed
