3. Important Installation Note (If you are installing)

If you are looking for the "feature" to select during installation or license configuration:

  • This is not a standalone full installer. It is an update that sits on top of the base OrCAD/Allegro 16.6 installation.
  • You must have the base 16.6 release installed first before applying the 16.60.004 update.

2. Understanding the Hotfix Numbering System

Cadence uses a specific versioning logic. The full string breaks down as follows:

  • 16.6: Major version (Base release).
  • 0: Minor revision (usually represents the base install).
  • 004: The hotfix sequence number.

Crucial distinction: This is not a major update or a "full installer." Hotfix 004 is an incremental patch that assumes you already have Cadence SPB 16.6 Base Release (16.60.000) installed. You cannot install hotfix 004 on a clean machine without the base software.

Historically, Cadence released over 100 hotfixes for the 16.6 branch (up to 16.6.115). The 16.60.004 hotfix is an early, but critical, accumulation of fixes addressing the most immediate post-launch issues.

5. Known Issues Introduced by .004

No software patch is perfect. Archival discussions reveal several regressions in 16.60.004:

3. Important Installation Note (If you are installing)

If you are looking for the "feature" to select during installation or license configuration:

  • This is not a standalone full installer. It is an update that sits on top of the base OrCAD/Allegro 16.6 installation.
  • You must have the base 16.6 release installed first before applying the 16.60.004 update.

2. Understanding the Hotfix Numbering System

Cadence uses a specific versioning logic. The full string breaks down as follows:

  • 16.6: Major version (Base release).
  • 0: Minor revision (usually represents the base install).
  • 004: The hotfix sequence number.

Crucial distinction: This is not a major update or a "full installer." Hotfix 004 is an incremental patch that assumes you already have Cadence SPB 16.6 Base Release (16.60.000) installed. You cannot install hotfix 004 on a clean machine without the base software.

Historically, Cadence released over 100 hotfixes for the 16.6 branch (up to 16.6.115). The 16.60.004 hotfix is an early, but critical, accumulation of fixes addressing the most immediate post-launch issues.

5. Known Issues Introduced by .004

No software patch is perfect. Archival discussions reveal several regressions in 16.60.004:

  • Gloss (auto-router post-process): Some users reported that the “Gloss” command would delete differential pair vias when set to “minimum bend” mode.
  • Backward compatibility: .sbp files saved in .004 could not be opened in 16.60.000 or .001 — a database revision bump occurred.
  • PSpice model library: The hotfix accidentally replaced the custom nom.lib with a default version, breaking user-defined model paths.

Cadence quickly released 16.60.005 (or encouraged moving to PU001) to mitigate these.
