Table 3-7: Logical Channel Number For Each SDI Channel
SDI Channel Direction Number of Reconfiguration
Interfaces
Logical Channel Number
0 Duplex 2 • 0: RX/TX channel
• 1: Tx PLL
1 RX and TX 3 (1 for RX and 2 for TX) • 2: RX channel
• 3: TX channel
• 4: TX PLL
2 Duplex 2 • 5: RX/TX channel
• 6: TX PLL
• Edit the reconfiguration logic source file to assign the logical channel number for the additional SDI
duplex instance, which occupies the SDI Ch2. The logical channel number specified in the source file is
the reconfiguration interface that is intended for dynamic reconfiguration. For example, if TX channel
is intended for dynamic reconfiguration,
tx_log_ch_num[2]
should be 5.
wire [7:0] rx_log_ch_num [0:NUM_CHS-1];
assign rx_log_ch_num[0] = 8'd0; // Duplex Rx channel share same
logical channel number with Tx
assign rx_log_ch_num[1] = 8'd2; // Rx channel
assign rx_log_ch_num[2] = 8'd5; // Duplex Rx channel
wire [7:0] tx_log_ch_num [0:NUM_CHS-1];
assign tx_log_ch_num[0] = 8'd0; // Duplex Tx channel share same
logical channel number with Rx
assign tx_log_ch_num[1] = 8'd3; // Tx channel
assign tx_log_ch_num[2] = 8'd5; // Duplex Tx channel
