Hi,when I simulated the Triple speed ethernet MAC,I added a data interface contro module to the mac,I found the signal ff_rx_data[7:0] have data stream out,but there are serval "00" bytes in the stream and the signal ff_rx_dsav was deasserted and rx_err[5:0]=6'b000110,how does that happen? I set the mac interface register as following: register offsetregister namevalue0x08command_config0x0080_00330x04scratch0xAAAAAAAA0x0Cmac_00x17231C00 0x10mac_10x0000CB4A 0x14 frame_length 0x5ee 0x18 pause_quant 0x0f 0x1C RX_section_empty 0x10 0x20 RX_section_full 0x10 0x24 TX_section_empty 0x100x28 TX_section_full 0x10 0x2C RX_almost_empty 0x08 0x30 RX_almost_full 0x08 0x34 TX_almost_empty 0x08 0x38 TX_almost_full 0x0A ox3c 0x00 0x5c 0x0c 0xe8 0x00 0xec 0x00
Hi,Thank you for your reply! Firstly,I added data stream to "ff_tx_data",then the gm_tx_d[7:0] have data out. secondly,I copy the out data and the signal of enable to gm_tx_d[7:0] interface.
