Nets

ODB++ can actually store nets in different ways. We support the basic net section - customized EDA based net info is not currently processed.

The netlist section begins with a declaration of the net names and assigns an index to each name:

$0 $NONE$
$1 BIDI_T4
$2 C_L_N
$3 C_L_P
$4 C_LO_N
$5 C_LO_P
$6 C2_LO_N
$7 C2_LO_P
$8 CLK_AZ_CML_N
$9 CLK_AZ_CML_P
$10 CLK_CML_N
$11 CLK_CML_P
$12 CLK_DCDC
$13 CLK_DCDC_2
$14 CLK2_AZ_CML_N

The next section in ODb++ defines coordinates on either the top or the bottom that label a net.

By reading this section, NETEX-O can assign a net to each geometry that it outputs.
