Coordinate Conventions Schematic coordinates in microns Y increases upward (VDD at top, GND at bottom) Symmetric pairs: mirror around x=0 Typical spacing: 3 units horizontal, 3 units vertical between rows Pins placed at the edges (x = +-6 or more) PDK Master Names PDK NMOS PMOS SMIC 130nm (smic13mmrf) n12 p12 TSMC 180nm nch pch Sky130 sky130_fd_pr/nfet_01v8 sky130_fd_pr/pfet_01v8 Params are PDK-specific. Always pass W/L via --params or JSON params field. Label Placement — Auto-Rotation When placing labels on terminals, pick rotation based on the stub direction rather than using a fixed angle. The stub direction is determined by the terminal geometry: Stub direction abs(rbDx) >= abs(rbDy) Recommended rotation Horizontal true R0 (0°) Vertical false R90 (90°) For schematic_label_instance_term_offset (label on a perpendicular branch off the stub), align the rotation with the branch direction, not the stub: branch \"up\" or \"down\" → R90 branch \"left\" or \"right\" → R0 This avoids overlapping labels on crowded ports (e.g., MOS gate rows) and matches what Virtuoso's \"Clean\" cosmetic preset produces. When stub geometry is degenerate (rbDx or rbDy is nil, e.g. MOS-stub path), fall back to the user-supplied rotation. Notes vcli schematic open must be called before other commands (opens cellview in GUI) conn uses schCreateWire for auto-routing between terminals wire uses exact coordinates — use when you need specific routing paths Global nets (vdd!, gnd!) use ! suffix in Virtuoso convention After build , always run check and save Always call dbClose after dbSave in SKILL loops that open cellviews programmatically; omitting it leaves views accumulating in Virtuoso memory across repeated invocations",
