4.2. HMC Interface Signals
The HMC Controller IP core's HMC interface connects to the external HMC device's link interface and main reset signal.
Signal Name |
Direction |
Description |
---|---|---|
hmc_lxrx[15:0] | Input |
Receiving lanes. Implements HMC specification LxRXP and LxRXN differential pairs. You must connect this data bus to the HMC device LxTXP bus. The Quartus® Prime Fitter assigns the correct pin to the negative signal automatically. |
hmc_lxtx[15:0] | Output |
Transmitting lanes. Implements HMC specification LxTXP and LxTXN differential pairs. You must connect this data bus to the HMC device LxRXP bus. The Quartus® Prime Fitter assigns the correct pin to the negative signal automatically. |
hmc_lxrxps | Input |
Link power reduction input. Implements HMC specification LxRXPS signal. The HMC Controller IP core sets the value of the RXPS field of the LINK_STATUS register to the value of this signal. You should connect this input signal to the HMC device LxTXPS output signal. |
hmc_lxtxps | Output |
Link power reduction output. Implements HMC specification LxTXPS signal. The IP core drives this signal with the value in the TXPS bit of the CONTROL register. You must connect this output signal to the HMC device LxRXPS input signal. |
hmc_ferr_n | Input |
Active-low fatal error indication from the HMC device. The HMC Controller IP core sets the value of the FERR_N field of the INTERRUPT_STATUS register to the value of this signal. You must connect this signal to the HMC device FERR_N signal. |
hmc_p_rst_n | Output |
Main reset signal to the HMC device. The IP core drives this signal with the value in the P_RST_N bit of the CONTROL register. You must connect this signal to the HMC device P_RST_N signal. |
