new and updated designs #18
Conversation
CDCA6 is like CDCA1 but uses s-bends. I will rework the other designs (CDCA3-5) with s-bends if time permits.

Hi Scott, I am wondering why you aren't using the CDC that includes the S-bend inside? This avoids the overlapping errors you have.

Hi Lukas - I didn't use the CDC p-cell with an S-bends (contra_directional_coupler) because I thought I saw in another thread that it had an issue with 0.75um WG width. I just tested that p-cell and I see that it works with the 0.75um WG width. However, I am iterating on a baseline CDC design (for which we have data) that uses the Contra_DC_custom p-cell and has non-equal inner and outer corrugation widths. I am hesitant to switch to the contra_directional_coupler p-cell, which only has equal inner/outer corrugation widths. I don't know what impact this parameter will have on device performance. |

Here is the comment on the CDC p-cell issue I was referring to: |

@mustafacc, what do you think? |

Withdrawing. I will rework using the contra_directional_couplerp-cell with s-bends (with symmetric corrugation) to satisfy DRC. |
