8.3.3 Rail Setup
Power rails are defined under the Pin Assignment tab, as shown in Figure 4. Click corresponding buttons to add or delete a rail. After a rail is added, AMON, DMON, EN, and MARGIN pins can be assigned to the rail. UCD90320 has 24 AMON pins, 8 DMON pins, 32 EN pins, and 24 MARGIN pins, thus can support up to 32 rails.
