I've try to add it again on this reply. The same message: " An error occurred. Please try again or contact your administrator." My initial problem was related to this question community.cadence.com/.../spectre-nodes-info-pin-names-different-than-what-is-in-schematic-or-input-scs spectre nodes info: pin names different than what is in schematic or input.scs   On that I didn't had any attachment. I was trying just some text formatting (inline code blocks) to make it readable. In the end I had to split it in the original message. Maybe there is a limit to the body message or it has some special (html) chars community.cadence.com/.../inteneded_5F00_message.txt . I've attached it as plain text, in case IT want to debug it. First line is the thread subject, then follow the message body. Thanks a lot for carring, Marcelhttps://community.cadence.com/general_topics/f/feedback-suggestions-and-questions/65985/testing/1408417Mon, 04 May 2026 15:07:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:8e44000a-ae72-4a0c-8d2b-8dfebd02df91Andrew Beckettmarcelpreda IT asked me how big was the file you were trying to upload? There's a 2MB limit and exceeding this can cause issues similar to what you described. I'm not sure that's entirely it, because that would only be relevant if you were adding the attachment and I'm not sure that's the only thing you tried?

I'm trying to start a thread in this forum, but no success. Either my message is to big, or something else (e.g. I've try some text formatting) but when I push Post the the page is "thinking", see attachment. I've try it in Chrome and Edge browsers, I've wait almost half hour, noting is happening. Some advice, should I skip text formatting?

Description of the issue: The crash happens during differential pair operations such as: Routing Slide/drag (tuning or adjusting) The application simply closes instantly (no warning, no crash dialog, no log that I can see) Environment: Tool: OrCAD X PCB Professional Version: 24.1-2024-S007 OS: Windows 11 Additional details: Happens consistently when working with differential pairs Not related to a specific net or design (occurs across multiple projects), some closes frequently and some less Single-ended routing seems stable No visible error messages or logs generated What I’ve tried: Restarting the tool and PC Testing with different designs Database check (no errors in log) Questions: Is there a known issue or patch for this? Any help or guidance would be greatly appreciated. Thanks!PCB Editordifferential pairOrCAD Xcrashhttps://community.cadence.com/general_topics/f/feedback-suggestions-and-questions/63326/why-i-can-t-insert-pictures-from-my-computer/1407901Tue, 03 Mar 2026 06:01:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:b80dce47-28c3-439e-b2bd-2a6c92f17053Zhifeng JinNo solution.

Looked into using SKILL commands but it is unfamiliar to me and it seems like there may be extensive additional programming to make it work. Additionally, I am using IC 25.1 and the bash terminal command that was suggested does not appear to add any Diva specific menus in Layout Suite XL. For now, I will read up on the migration guide.https://community.cadence.com/general_topics/f/feedback-suggestions-and-questions/65591/ncsu-techlib-ami06---diva---assura-files/1407346Mon, 22 Dec 2025 20:44:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:e2d8940c-d074-4f15-9d15-fbbd41f31eedAndrew BeckettIf you really need to do this (you could just continue to use Diva - see Looking for Diva menu in ICADV12.x/ICADVM18.1/ICADVM20.1/IC23.1 release if it's just the menus you're missing), then look at /doc/DivaToAssura/DivaToAssura.pdf - also can be found online here: Diva to Assura Migration Guide -- Preface - Preface You also don't need to migrate the tech.db or techfile (I assume that's the ASCII tech file).

Cadence tools cannot read files encrypted for HSPICE (a Synopsys simulator) in the same way that their tools can't read files encrypted for Spectre (a Cadence simulator).

The devices in use, according to the PDK model files, include internal body diodes as part of their structure. Setup: VDD = 20V supply Layout passes DRC, LVS, and ANN SUB terminals for both NMOS and PMOS are connected to GND and VDD respectively Issues Encountered: In Calibre PEX, I see warnings like: “Area for diode cannot be 0.0, reset to 1e-12” “Layout instances ignored due to invalid master” In Assura layout extraction, I can Diode noted “unmatched” In Spectre post-layout simulations, DC and transient behavior significantly diverges from schematic-level results. I suspect that leakage through internal body diodes at high voltage (20V) is causing simulation instability or unexpected current paths—possibly due to how the substrate terminals are connected or how the extraction tool interprets the parasitics. Questions: What is the recommended way to connect SUB terminals in high-voltage devices to avoid body diode conduction or leakage? How can I configure Calibre PEX (or Assura) to extract accurate area/perimeter values and avoid diode mismatch warnings? Since we cannot control or set the internal Diode no matter in schematic or layout. Is there a specific LPE or netlisting flow required to properly handle HV parasitics and diode modeling in this process? Any help on preventing diode-related leakage and ensuring post-layout accuracy at high voltage mosfets or any experience about the HV PDK would be greatly appreciated.spectre simulationenvironmental variablesimulation problemanalogTransient simulationdesignhttps://community.cadence.com/general_topics/f/feedback-suggestions-and-questions/31357/cadence-16-6-orcommn-2302/1405017Wed, 14 May 2025 06:14:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:7f44d3f3-ec18-46cd-a881-fc3830881439ZZ202505137120Hi,the adress you gived has died,can you give me a new one.
