| GT Selection | 选项基于器件/封装四通道组。例如： Quad X0Y1 Quad X0Y2 Quad X0Y3 GTM_DUAL_X0Y0 如果 GT 类型选为 GTM，则 GTM 双通道列表可供选择。例如：GTM_DUAL_X0Y0 GTM_DUAL_X0Y1 |
Quad X0Y0 |
| Lane-00 到 Lane-03 | 根据器件/封装自动填充。 例如，如果 Speed = 50G 且 Num of Cores = 2（或者 Speed = 40G 且 Num of Cores = 1）并且 GT Selection = Quad X0Y1，则 4 个 GT 通道为： X0Y4 X0Y5 X0Y6 X0Y7 |
