Gigafirm TEST Coupon "GT"
GT-4 TEST Coupon
At the time of the FPGA board development which equips high-speed wiring, Test coupon is designed by the same Substrate and a wiring configuration.
GT4 is imitating the conditions of PCI express. It is applicable to FPGA, SFP+, SATA, SAS, CLOCK, LVDS, and LVPECL. AMF2013 session.

Gigafirm Research and development
From the developer viewpoint, the simulation of the subject which was a question is carried out, and the test coupon is created and verified. The contents will be exhibited from now on.
Although we are newborn small companies, we would like to contribute to society through an engineer's support.
