// Description: This is the EMAC block level Verilog design for the Virtex-5
// Embedded Ethernet MAC Example Design. It is intended that
// this example design can be quickly adapted and downloaded onto
// an FPGA to provide a real hardware test environment.
//
// The block level:
//
// * instantiates all clock management logic required (BUFGs,
// DCMs) to operate the EMAC and its example design;
//
// * instantiates appropriate PHY interface modules (GMII, MII,
// RGMII, SGMII or 1000BASE-X) as required based on the user
// configuration.
//
//
// Please refer to the Datasheet, Getting Started Guide, and
// the Virtex-5 Embedded Tri-Mode Ethernet MAC User Gude for
// further information.

在这个文件中，一共例化了两个模块，第一个模块，gmii_if是可以找到的。
但是，第二个就无法找到。
在emac文件中，例化了一个模块

// Instantiate the Virtex-5 Embedded Ethernet EMAC
//--------------------------------------------------------------------------
TEMAC v5_emac
(
.RESET (RESET),
// EMAC0
.EMAC0CLIENTRXCLIENTCLKOUT (EMAC0CLIENTRXCLIENTCLKOUT),

.EMAC0CLIENTRXSTATS (EMAC0CLIENTRXSTATS),
.EMAC0CLIENTRXSTATSVLD (EMAC0CLIENTRXSTATSVLD),

当我使用debussy打开的时候，也是找不到emac模块的。 |
