Limitations:

a.       The KLayout DRC decks are experimental and the results don’t match golden deck exactly. It can only be used for initial check. Waiver requests need to be done with golden deck.

b.       The KLayout DRC decks are relatively slow and may have difficulties to handle large design files or a large amount of violations. We recommend to run KLayout DRC on small sub-design first.

Options:

1.       The KLayout DRC engine supports a few options, including hierarchical mode and tiling. Since our KLayout DRC deck is only intended to check small design, the hierarchical mode and tiling options are by default turned off. Please follow the steps listed below to view and set those options using the switches provided in the DRC deck. When using tiling option, the tiling boundary region may have incorrect results. For details about KLayout DRC runset and options, please check out Klayout DRC document.

a.       Open the Macro Development environment using Fn+F5 .

b.       Go to the DRC tab. Find the deck (ACTIVE_PIC or Passive_PIC) that you are using. Please do not change the main deck DRC_AIM_DECK.

c.       Open the deck and update switches as shown in Figure 3.

d.       Save the deck and close the Macro Development environment.

e.       Run the DRC deck as normal.
