TEMAC_SINGLE
Primitive: Tri-mode Ethernet Media Access Controller (MAC)
Introduction
The TEMAC_SINGLE library primitive provides the ports and attributes necessary to instantiate the Virtex®-6
FPGA Embedded Tri-Mode Ethernet MAC. Because it encompasses SecureIP encrypted HDL, it is also used for
functional and timing simulations. This primitive can be simplified for specific customer needs by using the
CORE Generator™ tool to create Ethernet MAC wrappers.
