Hardware Design Support

Title Description
IBIS IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
Reference oscillator circuit constants Oscillator circuit constants provided for reference by Murata Manufacturing, Kyocera and Nihon Dempa Kogyo.
