- fix grating couplers, which had 2 fibre targets, and simulations wouldn't run
0.3.16
- SEM layer: changed from 26 to 200, to avoid conflict with other PDKs - for process development in 90 nm slab: grating coupler ebeam_gc_te1550_90nmSlab - for 90 nm slab: added rib waveguide type - separating out each cell into their own GDS file
0.3.15
- added ebeam_dc_te1550 layout and model: only supports coupler length parameter
