Signal Direction Description
dlup
Output When asserted, indicates that the Hard IP block is in the Data
Link Control and Management State Machine (DLCMSM) DL_
Up state.
dlup_exit
Output This signal is asserted low for one pld_clk cycle when the IP
core exits the DLCMSM DL_Up state, indicating that the Data
Link Layer has lost communication with the other end of the
PCIe link and left the Up state. When this pulse is asserted, the
Application Layer should generate an internal reset signal that is
asserted for at least 32 cycles.
ev128ns
Output Asserted every 128 ns to create a time base aligned activity.
ev1us
Output Asserted every 1 µs to create a time base aligned activity.
hotrst_exit
Output Hot reset exit. This signal is asserted for 1 clock cycle when the
LTSSM exits the hot reset state. This signal should cause the
Application Layer to be reset. This signal is active low. When this
pulse is asserted, the Application Layer should generate an
internal reset signal that is asserted for at least 32 cycles.
int_status[3:0]
Output These signals drive legacy interrupts to the Application Layer as
follows:
• int_status[0]: interrupt signal A
• int_status[1]: interrupt signal B
• int_status[2]: interrupt signal C
• int_status[3]: interrupt signal D
l2_exit
Output L2 exit. This signal is active low and otherwise remains high. It is
asserted for one cycle (changing value from 1 to 0 and back to 1)
after the LTSSM transitions from l2.idle to detect. When this
pulse is asserted, the Application Layer should generate an
internal reset signal that is asserted for at least 32 cycles.
lane_act[3:0] Output Lane Active Mode: This signal indicates the number of lanes that
configured during link training. The following encodings are
defined:
• 4’b0001: 1 lane
• 4’b0010: 2 lanes
• 4’b0100: 4 lanes
• 4’b1000: 8 lanes
