ZCU106 board with "IOSTANDARD error" during Implementation

Jump to solution

I'm using the Xilinx ZCU106 development board and during implementation I received a error message as shown below.

I match the same IOSTANDARD in my xdc file as what Xilinx recommend. for the I2C1_SDA_and I2C1_SCL signals in my design.

-------------------------------------------------------------------------------------------------------------------

[DRC BIVB-1] Bank IO standard Support: Bank 65 has incompatible IO(s) because: The LVCMOS12 I/O standard does not support a drive strength of 12. Move the following ports or change their properties:
i2c_scl

---------------------------------------------------------------------------------------------------------------------

But The xdc that comes with this board also calls out the same IO STANDARD for LVCMOS12 as shown:

##############################################################################
##### ZCU106 Rev1.0 XDC 02/10/2018
#############################################################################

set_property PACKAGE_PIN AL21 [get_ports "PL_I2C1_SDA_LS"] ;# Bank 65 VCCO - VCC1V2 - IO_L7N_T1L_N1_QBC_AD13N_65
set_property IOSTANDARD LVCMOS12 [get_ports "PL_I2C1_SDA_LS"] ;# Bank 65 VCCO - VCC1V2 - IO_L7N_T1L_N1_QBC_AD13N_65

set_property PACKAGE_PIN AH19 [get_ports "PL_I2C1_SCL_LS"] ;# Bank 65 VCCO - VCC1V2 - IO_T1U_N12_65
set_property IOSTANDARD LVCMOS12 [get_ports "PL_I2C1_SCL_LS"] ;# Bank 65 VCCO - VCC1V2 - IO_T1U_N12_65

--------------------------------------------------------------------------------------------------------------------------------

Please help.

Hi,

I see that error is not for LVCMOS12, instead error message says drive strength of 12mA is not supported.

I think Bank 65 is HP bank & in HP bank, drive strength 12mA is not supported for IO standard LVCMOS12.

Changes the Drive strength to the particular pin.
