Layan - an Electromagnetic Circuit Layout Simulation Program

Have you ever designed a printer circuit board for a project, especially a high-frequency RF one, only to find that when you have built the circuit it does not perform entirely as predicted? Even if you use circuit simulation software, such as Analyser IIITM or Pulsar TM to test your design and then use Easy-PC Professional TM to produce the PCB design, you could still find that there are some undesired products or spurious signals produced, or simply that the circuit does not work as predicted, or even not at all!
