Hi Darshan, you may want consider to use a simulator that can be used for both domain and give consistent results in both domain. The simulator, I am referring to is Nexxim and you may want check its functionalities at our web site www.ansoft.com Giancarlo ----- Original Message ----- From: "Darshan Mehta" <darshanmehta2k@xxxxxxxxx> To: <si-list@xxxxxxxxxxxxx> Sent: Thursday, November 04, 2004 6:30 AM Subject: [SI-LIST] Frequency v/s Time Domain analysis Hi Experts, I am new user in High Speed Domain. I am just wondering which simulation method is good, either Time Domain or Frequency Domain. I have a board with Direct Digital Synthesizer which has Digital interface on one side and Analog interface on other side. The Analog frequency output can be from 0 Hz to 150 MHz. I am not sure whether I should do Digital simulation or Frequency simulation. Could you please tell me, in which scenario I should go for Frequency domain Analysis like plotting the graph of Frequency v/s Loss, Frequency v/s Amplitude etc and in which case I should opt for Time domain Analysis? Thanks! Have a Great Day. -Darshan Mehta --------------------------------- Do you Yahoo!? Check out the new Yahoo!
