Hi there,
I wanna use in my design 4 EMACs. I have used CORE Generator to generate 2 Virtex 5 Embedded Tri-Mode Ethernet MAC wrappers 1.4 (each contains 2 EMACs). In fact, they have the same properties except of MAC addresses. I have written the top module where I used two generated components and made control for them. But after I started simulation, just one EMAC0 and EMAC1 generate txclient and rxclient clocks, EMAC2 and EMAC3 don't. I'm using in my project XC5VLX50T chip, which has
4 EMACs onto. It looks like EMAC2 and EMAC3 clock outputs go to undefined states after around 1 us.
Could someone tell me what's wrong there? or what is the right way to use 4 EMACs together?
Cheers, Vlad.
