<https://github.com/IHP-GmbH/IHP-Open-PDK/issues/406|#406 KLayout LVS scripts should be platform-agnostic>
Issue created by <https://github.com/martinjankoehler|martinjankoehler>
## Problem

• `ihp-sg13g2/libs.tech/klayout/tech/lvs/sg13g2.lvs` uses Linux-specific system executables `pmap`/`tail`  
   • fails on Windows (at least outside WSL), as both `pmap`/`tail` are not available by default on this platform  
   • fails on macOS, as `pmap` is not available by default on this platform
• `libs.tech/klayout/tech/lvs/sg13g2_full.lylvs` contains a custom implementation `get_memory_usage`

## Solution

• KLayout already offers the Ruby API `RBA::Timer.memory_size` on all platforms
