```text
Is passing DRC strictly required to tapeout? Is there any waiver system? For example I want to make topmetal "pads" smaller than design rule pad sizes, as I want to post-process dies/wafers to add additional layers to the design.

Tim wants wsrun-2 to follow the DRC rules much more strictly, as per the PDK docs.

The only rule I can find for the pad layer is for the top metal overlap: https://gf180mcu-pdk.readthedocs.io/en/latest/physical_verification/design_manual/drm_09_1.html
All the other rules are guidelines: https://gf180mcu-pdk.readthedocs.io/en/latest/physical_verification/design_manual/drm_09_2.html
However, as there is no mention of a minimum pad width anywhere, wafer.space has to assume a minimum width of 40x40 according to PAD.1.

Unfortunately, they don't apply to our use case and specify different numbers. While the solder bump (solder ball) rules specify a min. passivation opening of 40um, the probe guidelines specify min. probe passivation opening of 50um.

There's an interesting note in the bond pad guidelines:

> These are just default numbers for DRC purpose only, however, these are VARIABLE and the customer is advised to use the appropriate value acceptable to their assembly house.

So I suppose there's no min. limit for the passivation opening specified, because they assume that you are going to use sane numbers anyway, in order to do the bonding process.

Well, if there is no maximum, then you could just have a completely open top of the chip with no passivation.

```text
Right. Technically, you could cover the entire chip with TopMetal (no upper density limit?) and open up almost the entire inside area. However, this would be pretty useless since you would then have TopMetal everywhere. Even then, I don't think it would be accepted for manufacture. The rules seem targeted at "normal" bonding applications.

So I guess it's fair to say the min. pad opening is 40x40um, and there's no way around this by opening up the whole chip.

Assuming this is "bond pad" rules, then I think each pad would also need to meet "PAD.5 MetalTop (2) overlap of Top_Via (3)" which just says 0.5... not > or <= etc... so I feel they must mean 'exactly 0.5'.
