Displays information about the LAB column interconnect, which routes signals throughout a column of MegaLAB™ structures (in APEX™ 20K, APEX™ II, and ARM®-based Excalibur™ devices) or LABs (in ACEX® 1K, FLEX® 6000, FLEX 10KE, and Mercury™ devices).
If you are using an APEX 20K or ARM-based Excalibur device, the section displays the number of lines, which includes those lines used as half-lines (that is, lines that traverse half of the device in a vertical direction) used by the LAB column interconnects, which are part of the FastTrack® interconnect.
If you are using an APEX II device, the section displays the number of line segments (which include half-lines) that are used in the LAB column interconnect channels, which are part of the FastTrack interconnect.
If you are using a ACEX 1K, FLEX 6000, or FLEX 10KE device, the section displays the number of lines used in the LAB column interconnects.
If you are using a Mercury device, the section displays the number of lines and half-lines used in the LAB column interconnects. The lines in these devices are separate entities from the half-lines.
Information is provided as follows for APEX 20K and ARM-based Excalibur devices:
| Heading | Description |
|---|---|
| MegaLAB Col. | Shows the MegaLAB column number where the LAB column interconnect is located. |
| Col. | Shows the LAB column interconnect number. This LAB column interconnect is located within the specified MegaLAB column. |
| Lines Available | Shows the total number of column interconnect lines available for use by signals in the design. |
| Lines Used | Shows the actual number and the percentage of column interconnect lines used by signals in the design. |
| Half-Lines Used | Shows the actual number and the percentage of column interconnect half-lines used by signals in the design. |
Information is provided as follows for APEX II devices:
| Heading | Description |
|---|---|
| MegaLAB Col. | Shows the MegaLAB column number where the LAB column interconnect is located. |
