请教一下各位大神大佬,GTP硬件引脚需要我们在XDC文件分配吗?我看原子哥例程里面在顶层模块有光口输入输出定义,但是没有找到引脚分配,是因为硬核不需要分配IP默认引脚吗?那为啥还要在模块里面定义输入输出端口呢?
module gtwizard_0_exdes #
(
parameter EXAMPLE_CONFIG_INDEPENDENT_LANES = 1,//configuration for frame gen and check
parameter EXAMPLE_LANE_WITH_START_CHAR = 0, // specifies lane with unique start frame char
parameter EXAMPLE_WORDS_IN_BRAM = 512, // specifies amount of data in BRAM
parameter EXAMPLE_SIM_GTRESET_SPEEDUP = "FALSE", // simulation setting for GT SecureIP model
parameter EXAMPLE_USE_CHIPSCOPE = 0, // Set to 1 to use Chipscope to drive resets
parameter STABLE_CLOCK_PERIOD = 10
)
(
input wire Q0_CLK1_GTREFCLK_PAD_N_IN,
input wire Q0_CLK1_GTREFCLK_PAD_P_IN,
input wire DRP_CLK_IN,
input wire RXN_IN,
input wire RXP_IN,
output wire TXN_OUT,
output wire TXP_OUT,
output wire [1:0] tx_disable
);
