8.2i EDK - ML505 BSB design results in an error when runing Platgen

Description

I downloaded the XBD file for the ML505 board from the web and created a design with external memory using the BSB, but when I run the design I receive the following error in Platgen:

"Error Message:

Solution

This is an error in the ML505 XBD file. It is fixed in EDK9.1i. For 8.2i users, please modify the DCM connections as follows.

BEGIN dcm_module

PARAMETER INSTANCE = dcm_0

PARAMETER HW_VER = 1.00.a

PARAMETER C_CLK0_BUF = TRUE

PARAMETER C_CLKIN_PERIOD = 10.000000

PARAMETER C_CLK_FEEDBACK = 1X

PARAMETER C_DLL_FREQUENCY_MODE = LOW

PARAMETER C_EXT_RESET_HIGH = 1

PORT CLKIN = dcm_clk_s

PORT CLK0 = sys_clk_s

PORT CLKFB = sys_clk_s

PORT RST = net_gnd

PORT LOCKED = dcm_0_lock

END

BEGIN dcm_module

PARAMETER INSTANCE = dcm_1

PARAMETER HW_VER = 1.00.a

PARAMETER C_CLK0_BUF = TRUE

PARAMETER C_CLKIN_PERIOD = 10.000000

PARAMETER C_CLK_FEEDBACK = 1X

PARAMETER C_DLL_FREQUENCY_MODE = LOW

PARAMETER C_EXT_RESET_HIGH = 0

PORT CLKIN = sys_clk_s

PORT CLK0 = ZBT_CLK_OUT_s

PORT CLKFB = ZBT_CLK_FB_s

PORT RST = dcm_0_lock

PORT LOCKED = dcm_1_lock

END
