Integrity 3D-IC multi-die co-design and warpage analysis
Cadence · Package architecture and warpage compensation
- Purpose
- Assess interconnect, hotspots, mechanical stress and warpage risk during architecture and physical design of 2.5D/3D multi-die systems. Use consistent design data to compare changes across die, interposer, package and system teams.
- Technical approach
- A hierarchical multi-technology database and planning interface coordinate die, package and PCB data with analysis tools such as Celsius. The workflow links planning and implementation to analysis feedback; solver requirements depend on the task.
- Scope of use
- Fits chiplet, stacked-die and heterogeneous-integration teams comparing stack-ups, placement and interconnect options across design domains. Confirm the analysis modules and modeling support needed for warpage at a particular process stage.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsAn integrated design flow does not establish that every warpage mechanism is modeled. Cure, reflow and sequential assembly require confirmation of material laws, process history and boundary conditions, with comparison against measurements.
What to prepareBLNKK suggests preparing stack-up/geometry, material data, power and temperature conditions, interconnect data and design variants. For warpage studies, include the relevant process stages and measured references to discuss inputs and calibration.
Confirm with the supplierAsk Cadence about versions, required modules/licenses, data exchange and integration with existing tools. Confirm support for the target process and material behavior, and request a representative analysis/calibration demonstration.
- Public evidence
- Cadence’s current page describes unified planning, implementation, signoff and multiphysics analysis. The 2021 datasheet explicitly lists thermal analysis and mechanical stress analysis for warpage; neither source validates prediction error for your package.
