To help diagnose and address these issues, Allegro X PCB Editor includes the Performance Advisor , a diagnostic utility integrated within the Database Check (DB Doctor) workflow. What is Performance Advisor? Performance Advisor is a specialized analysis tool that examines the PCB design database and identifies conditions that may contribute to degraded application performance. Instead of manually investigating potential causes, designers can use Performance Advisor to pinpoint database settings, constraint configurations, and design characteristics that may be impacting responsiveness. The tool provides actionable recommendations that help improve design efficiency and overall editing performance. Benefits of Using Performance Advisor By routinely running Performance Advisor, users can: Identify database-related performance issues before they become critical. Detect constraint configurations that may cause slow editing operations. Receive practical recommendations for improving design responsiveness. Optimize shape handling and database settings for large designs. Improve overall PCB layout productivity and user experience. How to Access Performance Advisor Performance Advisor is available through the Database Check (DB Doctor) utility in Allegro X PCB Editor. Navigation Path:Tools → Database Check Running Database Check launches the analysis process, where Performance Advisor evaluates the current design and presents any detected performance concerns along with recommended corrective actions.</description></item><item><title>Forum Post: RE: TCl script to replace selected parts with a component from library</title><link>https://community.cadence.com/cadence_technology_forums/pcb-design/f/allegro-x-scripting-tcl/59683/tcl-script-to-replace-selected-parts-with-a-component-from-library/1434952</link><pubDate>Fri, 16 Oct 2026 09:01:00 GMT</pubDate><guid isPermaLink="false">75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:f40af384-46b5-48ba-a3b6-660c6133c226</guid><dc:creator>PatEscher</dc:creator><description>CadAP can you provide information what the following variables are doing? bUpdate: int bNewVersion: int updateDPfromLib: int when we use RepalceInst ..... 1 1 1 1 1, then we ecounter an OrCAD crash when afterwards trying to do an LinkDatabasePart. so it seems that it is related to these booleans (I suspect it is bUdate or bNewVersion)</description></item><item><title>Forum Post: RE: trying to load a .olb librray file</title><link>https://community.cadence.com/cadence_technology_forums/pcb-design/f/allegro-x-scripting-tcl/74699/trying-to-load-a-olb-librray-file/1434951</link><pubDate>Thu, 15 Oct 2026 14:08:00 GMT</pubDate><guid isPermaLink="false">75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:84ddc1e3-ef7e-4a47-9397-c49b174d09a5</guid><dc:creator>digital1</dc:creator><description>Hi TechnoBobby Sorry I didn&amp;#39;t make myself clear i have already created a dsn project and i want to load the .opj file into the design under the project window unfortunately your answer loaded the .olb file into a differnt session than my original design.

If this is too low then your etch may not escape the pin and turn to sharply. So click on your pin to start your diff pair. In the &amp;quot;Options Pane&amp;quot; check to see if the actual miter is at a minimum 2xwidth. You can change that to a higher value to see how the diff-pair responds. If the Miter is set to something like 1xwidth the etch will turn too sharply and not escape the pins as you want. Its also possible to use single trace mode. In that mode you route off the pin a certain distance then left click to stop routing, next right click and uncheck single trace mode. The other pin should route in to match the etch you started. So click on pin both diff-pairs appear. Right click and choose &amp;quot;Single Trace mode&amp;quot; Rote off the pin and left click to stop routing. Right click and uncheck &amp;quot;Single Trace mode&amp;quot; Let us know if it works. More than likely the trouble is related to the miter. A good value for Pad Entry Factor is 75 !</description></item><item><title>Forum Post: RE: Allegro X Capture will not launch again after closing the application</title><link>https://community.cadence.com/cadence_technology_forums/pcb-design/f/allegro-x-capture-cis/70340/allegro-x-capture-will-not-launch-again-after-closing-the-application/1434911</link><pubDate>Fri, 09 Oct 2026 20:08:00 GMT</pubDate><guid isPermaLink="false">75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:7a05369f-655e-4435-92b0-7f868cb34297</guid><dc:creator>gvellet</dc:creator><description>I noted the same problem with Orcad capture 24.1 and also after updating to 25.1.

The CIS Standard BOM typically reports properties that have been transferred into the design. If a property is visible in CIS but is not marked for Transfer to Design, it may appear blank in the CIS BOM output. Try enabling Transfer to Design in Options &amp;gt; CIS Configuration &amp;gt; Setup for the affected properties, updating the components from the database, and generating the BOM again.
