IRIGtimeS implements an IRIG 200-04 compliant time synchronization slave on FPGA devices. This IRIG-B slave IP has been designed to support all the IRIG-B coded expressions as well as DCLS and AM modulations in order to provide maximum flexibility.
This IRIG-B slave IP receives IRIG-B frames each second, getting the time information (seconds, minutes, hours, days, years, control functions and binary straight seconds) depending on the IRIG-B time code. This IP implements a 64-bit internal timer in order to provide the timestamp (in seconds) and nanoseconds value. This timer is synchronized in value and frequency with the received IRIG-B time information. This IP has been designed to provide autonomous operation, requiring as less con figuration as possible.
IRIGtimeS is supported on the following Xilinx FPGA Families:
- 7-Series (Zynq, Spartan, Artix, Kintex, Virtex)
- Ultrascale (Kintex, Virtex)
- Ultrascale+(Zynq MPSoC, Kintex, Virtex)
- Versal
- Managed Ethernet Switch IP Core for Xilinx Vivado Tool -
It is designed to be easily integrated in your FPGA designs by taking advantage of the new Xilinx Vivado Tool, that allows to use the IP Cores in a graphical user interface and configure IP parameters in an easy way.
