Change Summary Tables¶
Geometry and Cost Engine Changes¶
The table below contains a row for each geometry or cost engine change. Each row lists the following:
- Process group to which the change applies
- Impact level of the change (High, Medium, or Low)
- Whether the change can or must be disabled using site variables. See also Site Variable Spreadsheets.
- Description of the change and its impact
Changes are geometry changes unless explicitly labeled Cost engine change in the description.
The entries are arranged alphabetically by process group.
You can use this table to guide you in performing Step 2 and Step 3 of impact assessment (see Impact Assessment Steps). Click on the name of a process group in the first column to get more information on changes for that process group.
| Process Group | Impact Level | Can be Disabled? | Must be Disabled with Prior CMVs? | Impact Description |
|---|---|---|---|---|
| PCB | Low | No | No | The Geometric Cost Drivers pane now displays two new properties of the Layer GCD: Dielectric Thickness and Dielectric Type. aPriori can now extract values for these properties from ODB++ files. There is no cost impact, since the cost model does not yet use the new properties; they are currently for informational purposes only. |
Before you upgrade, review the process groups you use, and identify the ones have that have changes with cost impact. Once you have determined whether to accept or disable each High-impact geometry or cost engine change for the process groups that you use, you can upgrade to the new release. If there are no High-impact geometry or cost engine changes, you can upgrade to the new release.
aPriori also recommends that you review the cost model changes as well as the Low- and Medium-impact geometry and cost engine changes for the process groups you use.
All Changes¶
The table below indicates which categories of change impact each process group, as well as the cost model versions supported in the last three releases.
Process names in the table’s first column link to process-group-specific sections which can help you to perform Steps 3 and 4 of your impact assessments (see Impact Assessment Steps). Each of the sections contains summary tables as well as change details grouped by the following three categories:
- Geometry or cost engine changes that could impact configured Digital Factories: these are changes that might impact costing even for Digital Factories that use earlier cost model versions.
- Bug fixes or small improvements to prior cost model versions that could impact configured Digital Factories: these are back-ported bug fixes, which might impact costing for Digital Factories that use earlier cost model versions.
- Cost model changes that do not affect configured Digital Factories: these are changes that do not affect costings with Digital Factories that use earlier cost model versions.
| Process Group | Geometry, Cost Engine, or Incompatible RDL Changes | Bug Fixes or Small Improvements to Prior Cost Model Versions | Changes to New Cost Model Version | Cost Model Versions Supported in the Last 3 Releases |
