Agilex® 7 FPGA F-Series Transceiver-SoC Development Kit User Guide
A.1. System Management
- Power management: Controls systems and FPGA power up and optional down sequence, supervises power regulators/switches status and manages power faults, supervises temperature ADC interrupt signals, and manages temperature faults.
- JTAG controller: Manages JTAG chain topology, JTAG master source and JTAG slaves by SW3.
| Schematic Signal Name | Description |
|---|---|
| EXT_JTAG_TCK/TDO/TMS/TDI | JTAG header J19 for Intel® download cable |
| FX2_Dp/n | Input port CN1 for onboard Intel® download circuit |
| HPS_GPIO[32:35] | Mictor 38 pin header on OOBE daughter card |
The Agilex™ 7 HPS JTAG slave can be accessed from either SDM dedicated JTAG pins or HPS dedicated I/Os. When it is accessed from SDM JTAG pins (FPGA_JTAG_TCK/TDO/TMS/TDI), SDM is chained with HPS inside FPGA part. When it is accessed from HPS dedicated I/Os (HPS_GPIO[32:35]), HPS is chained externally by PCB traces.
| Mode | SW3 [8:6] | SW3[5][2][1] ON: Bypass from chain OFF: Enable in chain |
Function |
|---|---|---|---|
| 000 | ON/ON/ON (Default) |
SW3.1 (SDM+HPS) SW3.2 (SysMAX) SW3.5 ( PCIe* ) |
Mode 1: Onboard Intel® download circuit act as the only JTAG Master Chained HPS with SDM nodes internally Mode 3: External Intel® download cable act as the only JTAG Master Chained HPS with SDM nodes internally |
| 001 | ON/ON/OFF | SDM is always enabled in the JTAG chain SW3.1 (HPS) SW3.2 (SysMAX) SW3.5 ( PCIe* ) |
Mode 2: Onboard Intel® download circuit act as the only JTAG Master Chained HPS with SDM nodes externally Mode 4: External Intel® download cable act as the only JTAG Master Chained HPS with SDM node externally |
| 100 | OFF/ON/ON | SW3.1 (SDM) SW3.2 (SysMAX) SW3.5 ( PCIe* ) |
Mode 7: Both onboard Intel® download circuit and OOBE act as JTAG Masters Separated HPS and SDM JTAG chains, OOBE only drive HPS Mode 8: Both external Intel® download cable and OOBE JTAG act as JTAG Masters Separated HPS and SDM JTAG chains, OOBE only drive HPS |
| 110 | OFF/OFF/ON | — | Mode 11: Both onboard Intel® download circuit and OOBE act as JTAG Masters Onboard Intel® download circuit only drive SDM, OOBE only drive HPS |
