A users perspective of EMC and signal integrity toolsA USERS PERSPECTNE OF EMC AND SIGNAL INTEGRI‘IY TOOLS M J Hawley and A J. Smith Introduction In the electronics industry the need for EMC software is extremely varied, ranging from board level analysis tools such as 2D field solvers to equipment and system level tools. It is mainly at the board level that the ability to simulate electromagnetic behaviour meets the user’s needs. Equipment or system level simulation is generally provided by extreme levels of model abstraction, and workstation levels of computing power, or by more representative models using supercomputer or Massively Parallel Processing, MPP, hardware. An exception to this notion is the clever combination of measured and simulated behaviour embodied in the EMC system level software known as ’TDAS’[l]. In response to the wi……
