• Thanks AndyL and Matthias for clearing the whole situation in detail. My advisor was curious about the issue as our design was returned at the last hour by the foundry. But with re-saving it with dxf, we could get the required result. So we were cur…

• Thank you Matthias for your reply. Sorry for late response due to new year holidays here at Korea. My problem was: I had designed two similar layout in a single reticle(dividing it into two). The only difference between those two layouts are the gra…

• Please follow this link. And thank you in advance. I am also too curious about that small difference. https://drive.google.com/drive/folders/1ImMmJTmVsCYnNk1Jyucp-L1vUonn8s3x?usp=sharing

• It's not just about visibility, the design looks pretty messed up. things have moved around the layout. So I don't think it is layer issue. Anyways, how can I upload my design? I can upload my sample design for you. So that you can help me figure ou…

• UPDATE: FIXED IT.. I think I made a mistake while designing. I used to save the file in gds while I was designing. I figured out that I need to save it in dxf during the design phase and only after finishing the design, I need to save as gds. This w…

• Thank you @Mathhias! I also think being able to change layer in PCell can ease many other design issues. And Thanks once again @David. Your suggestion really helped. Although I tweaked your idea a little bit, it was useful. Since I had more than 100…

  in How can I move entire an entire layer layout into another layer? Comment by photonicsbishal February 2018
• Thank You for your reply. But, I am trying to move texts (Instance -> Basic Library -> Text) to main layout layer. So when I tried the way you explained, a message popped up saying "Nothing selected to switch layer for", although all…

• Thank you, Professor! I will look forward to the release of your documentation.

• Thank you davidhutch.. Actually, I was also doing the same trick. I used to add a small straight waveguide at the end of each input and outputs so that the resulting value becomes whole number. Then choosing 1um grid I am snapping it quickly. But I …

  in How can we auto connect waveguides/wires with other components properly? Comment by photonicsbishal February 2018
• Thanks! I used the GSiP but the snapping tool didn't work with my S-bends and MMIs. I am trying to design an MMI tree so I need to snap a lot of bends with MMIs. This is time consuming and critical. So I am trying to connect it out manually.

• Thank you Professor Chrostowski ! I have followed your book as well as tried the SiEPIC-EBeam PDK too but I do have my own optimized grating coupler, bends and other structure. So, I was looking for some way of connecting mine components directly as…
