The latest developments on AI applications and high-performance computing solutions demands ultra fast communication resulting in compact integrated circuits working at high operating frequencies. PeakView® is at the forefront of the AI revolution by providing the necessary tools to develop the chips for the latest technology requirements. At these high frequencies, EM effects such as skin depth, EM coupling, and conductive losses become critical at every stage of the design process, and with PeakView®, users have access to powerful EM analysis tools for manufacturing with confidence.
PeakView®’s EM Analysis Tools
Visualization of the 3D Mesh
- Besides reliable process technology data (material properties, layer thickness, etc) and boundary conditions, the mesh/discretization is one of the key parameters in accurate EM simulations.
- Mesh verification is an important step before EM simulation, and PeakView®’s GUI incorporates a field visualization window that provides detailed views of the 3D mesh that is indeed by the EM solver.
- PeakView®’s mesh visualizations delivers different types of mesh views including transparent, gray scale, colored mesh on layers and color mesh on nets.
- Net-based and layer-based mesh visualization provide a great insight when dealing with complex layouts that includes coils, MIMCaps, etc. It also helps when dealing with multi-layer layouts, including PeakView®‘s 3DIC solution for dealing with multiple process technologies.
Advanced 3D Visualization of EM Fields
- Field visualization is integrated to PeakView®’s GUI, delivering a comprehensive understanding of the EM simulations results based on voltage, current density, current density vectors and charge density.
- No need for third-party tools, and visualization parameters are available across all frequencies and ports.
- Field visualizations allows several interactive options such as 3D rotations and zooming capabilities, layer-based and net-based display, color bar range control, and visualization export to .svg and .vtp file formats.
3D EM Field View Animations
- Animation is one of the powerful EM field visualization analysis, which is available for any EM parameters (voltage, current density, charge density, etc) at all simulation frequencies.
- Current density animation is critical for analyzing the induced current density to identify critical parts of the layout, where EM coupling may exceed design requirements.
Port-Dependent EM Field Visualization
- PeakView®’s EM field visualization allows multiple types of excitations, where designers can apply different voltage levels to multiple ports in the layout, resembling their schematic test bench.
- Port-dependent visualization brings EM analysis to a higher level, where realistic EM performance is analyzed at different design stages.
EM / Visualization Post-Processing
-
- Traditionally EM analysis for multiple-port structure was done through circuit simulation test bench by drawing an schematic and manually connecting multiple ports to excitation ports, ground, etc.
- The whole procedure is inefficient, and EM insight is limited without corresponding visualization.
- PeakView® EM/Visual Post-processing provides the capabilities do EM analysis in PeakView® GUI environment without switching to circuit simulators.
-
- Short circuit between two ports
- Grounding ports (VSS, gnd)
- Assignment of 50ohms load to different ports
- Differential/Common mode excitation
- Even/odd mode excitation for transmission lines
- Referenced port excitation/local ground definition
