I've looked at the vertical migration between Arria 10GX parts and I'm wondering if there is anything stopping someone from making a board that can also support an SX part.
When I put the two pin-outs (I'm referring to the F29 package here) beside each other in Excel there are exactly two dozen pins that don't have the same description. A lot of them are gnd in the GX part and vccl_hps in the SX part. So, if I were to address these two dozen pins with zero ohm resistors, and populate those resistors according to which part I wanted to place on the board, what other problems would I run into?Link Copied

Hi Bgrattan, Do you want to use same board for both GX & SX device using socket? if yes than Check whether configuration/dedicated pins are in same location.(For pick and place). If you have soc project build on Arria 10 SX it may not work (depends on IP) so take care in IP's . While designing a board, bring those two dozen trace on top layer.

Thanks. It occurred to me that I should have pointed out that my analysis was for the AX027 part vs. SX027. If anyone has heard of someone designing a board that can accommodate either SX or GX parts, I'd be interested in their experience.
Also, if anyone is interested, here are the pins that are different: AX027 SX027 PIN GND VCCIO_HPS H13 GND VCCIOREF_HPS J13 GND VCCL_HPS K14 GND VCCL_HPS L13 GND VCCL_HPS L14 GND VCCL_HPS M13 GND VCCPLL_HPS J14 NC GPIO2_IO0,NAND_ADQ0,SDMMC_DATA0,QSPI_CLK F12 NC GPIO2_IO1,NAND_ADQ1,SDMMC_CMD,QSPI_IO0 G16 NC GPIO2_IO10,NAND_ADQ4,UART1_CTS_N,SDMMC_DATA6,SPIM0_SS0_N,EMAC2_MDIO,I2C_EMAC2_SDA E12 NC GPIO2_IO11,NAND_ADQ5,UART1_RX,SDMMC_DATA7,SPIS0_CLK,EMAC2_MDC,I2C_EMAC2_SCL G15 NC GPIO2_IO12,NAND_ADQ6,UART1_TX,QSPI_SS2,SPIS0_MOSI,EMAC0_MDIO,I2C_EMAC0_SDA K15 NC GPIO2_IO13,NAND_ADQ7,UART1_RX,QSPI_SS3,SPIS0_SS0_N,EMAC0_MDC,I2C_EMAC0_SCL F13 NC GPIO2_IO2,NAND_WE_N,SDMMC_CCLK,QSPI_SS0,BOOTSEL2 D12 NC GPIO2_IO3,NAND_RE_N,SDMMC_DATA1,QSPI_IO1 J12 NC GPIO2_IO4,NAND_ADQ2,SDMMC_DATA2,QSPI_IO2_WPN H12 NC GPIO2_IO5,NAND_ADQ3,SDMMC_DATA3,QSPI_IO3_HOLD F14 NC GPIO2_IO6,NAND_CLE,SDMMC_PWR_ENA,SPIM0_SS1_N,SPIS0_MISO,BOOTSEL1 G13 NC GPIO2_IO7,NAND_ALE,QSPI_SS1,SPIM0_CLK,BOOTSEL0 J15 NC GPIO2_IO8,NAND_RB,UART1_TX,SDMMC_DATA4,SPIM0_MOSI,EMAC1_MDIO,I2C_EMAC1_SDA H15 NC GPIO2_IO9,NAND_CE_N,UART1_RTS_N,SDMMC_DATA5,SPIM0_MISO,EMAC1_MDC,I2C_EMAC1_SCL F16 NC HPS_CLK1 G14 NC HPS_nPOR K11 NC HPS_nRST K12- Mark as New

Hello, you may have to consider the fact if you are using SX device, the HPS EMIF I/O is located on the FPGA I/O bank. Hence, it is not just the matter of the power pins and the HPS Dedicated I/Os (there are HPS 17 dedicated I/Os in Arria 10). You will need to make sure that the board reserves the HPS EMIF I/O so that the HPS in the SX device can use them
