Displays information about the number of lines used by the ESB Column interconnect, which is part of the FastTrack® interconnect and routes signals alongside Embedded System Blocks (ESBs).
If you are using an APEX™ 20K or ARM®-based Excalibur™ device, the section displays the number of lines and half-lines (that is, lines that traverse half the device in a vertical direction) used by the column interconnect channels.
If you are using an APEX™ II device, the section displays the total number of line segments used by the column interconnect channels.
This section is omitted if you specify an ACEX® 1K, Cyclone™, FLEX® 6000, FLEX 10KE, MAX® 3000, MAX 7000, Mercury™, Stratix™, or Stratix™ GX device for compilation.
Information is provided as follows for APEX 20K and ARM-based Excalibur devices:
| Heading | Description |
|---|---|
| Col. | Shows the ESB column interconnect channel number. |
| Lines Available | Shows the total number of column interconnect lines that are available for use by signals in the design. |
| Lines Used | Shows the actual number and percentage of column interconnect lines used by signals in the design. |
| Half-Lines Used | Shows the actual number and percentage of column interconnect half-lines used by signals in the design. |
Information is provided as follows for APEX II devices:
| Heading | Description |
|---|---|
| Col. | Shows the ESB column interconnect channel number. |
| Line Segments Used | Shows the total number of column interconnect lines that are available for use by signals in the design. |
