| GT Type | GTH, GTY, and GTM, GTYP | GTY |
| GT Selection | Options based on device/package quad groups. For
example: Quad X0Y1 Quad X0Y2 Quad X0Y3 GTM_DUAL_X0Y0 If the GT type is selected as GTM, then the GTM Dual List is available for the selection. For example: GTM_DUAL_X0Y0 GTM_DUAL_X0Y1 |
Quad X0Y0 |
| Lane-00 to Lane-03 | Auto filled based on device/package. For example, if Speed = 50G and Num of Cores = 2 (or Speed = 40G and Num of Cores = 1) and GT selection = Quad X0Y1, then the four GT lanes are: X0Y4 X0Y5 X0Y6 X0Y7 |
