Hi,
I got a problem when I use the RapidIO IP in my Cyclone V GTD5D7 custom board.
Here are some background that, I have another USER Serdes (x1) at the Serdes channel 0. And PLL at channel 1 to provide clock for user serdes, RAPIDIOX2_IP1 and RAPIDIOX2_IP2.
I can pass the placement in Quartus II(13.1) when I only enable the first RapidIOX2 IP. But when I enable the second one, the placement will fail at that
“Error (11687): srio_tx_data[3](n) is assigned to PIN_K1, srio_tx_data[1](n) is assigned to PIN_W3, channels cannot be placed in the same triplet.”
“Error (11688): srio_tx_data[3](n) is assigned to PIN_K1, srio_tx_data[1](n) is assigned to PIN_W3, channels cannot be placed in the same quadrant.”
Where the srio_tx_data[0] and[1] are used for the first RapidIOX2 IP and the [2] and [3] are for the second.
From the chip planner, it fails once placed the first RapidIO IP.
It seems the RapidIO IP is not placed at the serdes channel that I set in pin assignment.
It will be so kind of you If anyone can tell me:
1. Can we put two RapidIO IP in the cyclone V GT D5D7 Chip?
2. Did I miss any rule on serdes usage which cause the failure on placement?
3. How can I force certain IP on certain serdes resource?
