Long Lines

The long lines bypass the switch matrices and are

intended primarily for signals which must travel a long

distance, or must have minimum skew among multiple

destinations. Long lines, shown in Figure 13, run

vertically and horizontally the height or width of the

interconnect area. Each interconnection column has

three vertical long lines, and each interconnection row

has two horizontal long lines. Additionally, two long

lines are located adjacent to the outer sets of switching

matrices. Two vertical long lines in each column are

connectable half-length lines, except on the ATT3020,

where only the outer long lines serve that function.

Long lines can be driven by a logic block or IOB output

on a column-by-column basis. This capability provides

a common low-skew control or clock line within each

column of logic blocks. Interconnections of these long

lines are shown in Figure 14. Isolation buffers are pro-

vided at each input to a long line and are enabled auto-

matically by the development system when a

connection is made.
