Matthias Koefferlein a3cecb2ebe WIP: enable multiple layout versions of one schematic circuit using 'same_circuit' 2019-09-30 23:08:15 +02:00
Matthias Koefferlein 550e2622bf Put more amphasis on net names to resolve ambiguities 
The problem was that with the floating test case, the
ambiguity resolution sometimes assigned the wrong pins
and floating pins/connected pins were swapped.

One option is to make the ambiguity resolver consider
the pin connection state when tenatively evaluating
nodes.

Another option is to put more emphasis on net names
and use them for ambiguity resolution. This has helped
here.

Matthias Koefferlein c543fe7a44 Added test for floating device terminals. 2019-08-24 19:42:00 +02:00
Matthias Koefferlein 3a93bc2162 Added test for mixed-hierarchy LVS case. 2019-08-24 00:13:38 +02:00
Matthias Koefferlein 3ae848bff4 Provide test case for spice reader with delegate for devices as subcircuits. Small bugfix in spice reader: wrong line number in warning. 2019-08-23 23:13:04 +02:00
Matthias Koefferlein 45cdefcf9a Provide strict mode for device classes, dmos3/dmos4 for LVS 2019-08-20 23:12:17 +02:00
Matthias Koefferlein afb5cea576 Added "device_scaling" to LVS 
Plus: added some missing files

Implementation details:
* scaling factor was introduced in DeviceExtractor::extract
* for easy implementation this is available in "sdbu"
* "sdbu" is made available in GSI
* to test this, the db::compare_netlist had to be enhanced to
  exactly check device parameters
* enhancement of LVS script framework and doc updates

Matthias Koefferlein 5dabd6093d Provide new 'align' feature in LVS for automatic circuit flattening. 2019-07-23 01:12:12 +02:00
Matthias Koefferlein 9d250d6df9 Using a larger branch complexity than default for LVS full test's netlist compare 
In addition: typo fixed, added doc for complexity configuration
parameters.

Matthias Koefferlein 6e6e449eef Consolidated test data for lvs:full - there are too many variants to support pure text compare. We use the netlist comparer now. 2019-07-21 09:20:44 +02:00
