4.2.3. Modifying Your Pin Assignments to Choose the Physical Location of the HBM2E Device
There are two HBM2E memory devices in Agilex™ 7 M-Series FPGAs. One HBM2E memory is on the top of the FPGA and the other is on the bottom. With the HBM2E FPGA IP you must add the assignments in your qsf file to choose the location of the HBM2e device.
You can choose top versus bottom device by specifying the pin assignment for the dedicated refclk pins for the UIB PLL and the NoC PLL.
Modify your qsf file with the following assignments to use top or bottom location of the HBM2e memory device:
Specifying the top HBM
To specify the top HBM, set these assignments:
Set_location_assignment PIN_AR36 -to uibpll_refclk_clk Set_location_assignment PIN_AN36 -to "uibpll_refclk_clk(n)" Set_location_assignment PIN_AU52 -to noc_clk_ctrl_refclk_clk
Specifying the bottom HBM
To specify the bottom HBM, set these assignments:
Set_location_assignment PIN_EC36 -to uibpll_refclk_clk Set_location_assignment PIN_ED35 -to "uibpll_refclk_clk(n)" Set_location_assignment PIN_EE56 -to noc_clk_ctrl_refclk_clk
