Attribute Changer

What's new in this version:

Features:
- Bugfix: #381 and more Some bugs fixed that happened specifically on MacOS. 1.) A segfault that happened in LVS 2.) Some classes were not properly registered for usage in scripts
- Bugfix: #493 LVS asserted on MacOS
- Enhancement: #586 As a safety feature, the stream writers now refuse to write layouts with cells carrying the same names. Writing such layers would result in corrupted or invalid layout files
- Bugfix: #589 (tentative) On Anaconda-based builds for MacOS 10.15 (Catalina) a loss of instances was observed. This could be traced down to compiler/library incompatibilities but not further.
- Enhancements: #591 Two enhancements in the macro editor: 1.) A crash happening when adding a new location was fixed 2.) The template selection popup can now be disabled by dismissing the tip dialog
- Bugfix: #592 Reading a file into a layout with unnamed layers caused problems with layer mapping specs
- Bugfix: #596 Library#_destroy was crashing the application. As this function must not be called, it's rerouted to "nothing" for backward compatibility
- Enhancement: #603 The "adjust origin" feature now allows specifying the target coordinates for the adjustment
- Bugfix: #610 An internal error happened for certain hierarchical configurations on netlist extraction
- Enhancement: LVS netlist compare The algorithm was improved to provide better reproducibility. The detection of matching paths in the presence of ambiguities was improved. In addition, the netlist compare now favours net names for resolving ambiguities. So if nets are named the same in the layout and the schematic, ambiguities are resolved based on these names. This is usually more efficient. A new function is available to turn this feature off: "consider_net_names(false)".
