A.1. System Management
- Power management: control systems and FPGA power up and optional down sequence, supervise power regulators/switches status and manage power faults, supervise temperature ADC interrupt signals and manage temperature faults.
- JTAG controller: Manage 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 on-board Intel download circuit |
HPS_GPIO[32:35] | Mictor 38pin header on OOBE daughter card |
Intel 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: On-board 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: On-board 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 On-board 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 & OOBE JTAG act as JTAG Masters Separated HPS and SDM JTAG chains, OOBE only drive HPS |
110 | OFF/OFF/ON | N/A | Mode 11: Both On-board Intel download circuit and OOBE act as JTAG Masters On-board Intel download circuit only drive SDM, OOBE only drive HPS |
