8. Modifying Single-Device .jam Files for Use in a Multi-Device JTAG Chain
The .jam file codes in this document are meant for a single-device JTAG chain. To use these codes in a multi-device JTAG chain, add instruction register (IR) and data register (DR) lengths of the devices in the chain other than the .jam file's target device.
- Check the instruction register lengths of all the other devices in the JTAG chain.
- IR length:
- Intel® FPGA and CPLD devices: 10
- Hardware processor system (HPS) in Intel® SoC FPGA devices: 4
- DR length in any device: 1
- IR length:
- Locate the PROCEDURE EXECUTE line in the .jam file codes and add codes in the following steps to new lines after it.
- If there are devices in the chain before the target device, add the following codes:
POSTIR <total IR length before the target device>; POSTDR <total DR length before the target device>;
- If there are devices in the chain after the target device, add the following codes:
PREIR <total IR length after the target device>; PREDR <total DR length after the target device>;
Other Devices Exist in JTAG Chain Before or After Target Device
For each example chain, add the codes after the PROCEDURE EXECUTE line:
- Download cable TDI → other device 1 (IR=10) → target device → download cable TDO:
POSTIR 10; POSTDR 1;
- Download cable TDI → target device → other device 1 (IR=10) → download cable TDO:
PREIR 10; PREDR 1;
- Download cable TDI → target device → other device 1 (IR=10) → other device 2 (IR=10) → download cable TDO:
PREIR 20; PREDR 2;
- Download cable TDI → other device 1 (IR=4) → target device → other device 2 (IR=10) → download cable TDO:
POSTIR 4; POSTDR 1; PREIR 10; PREDR 1;
