Design a modern flat-style SVG app icon for a semiconductor analytics platform named “iEDA”. Create a square rounded app icon with a centered, diamond-shaped wafer outline (a square rotated 45 degrees) in white thick stroke. Inside the wafer, add a subtle grid of thin lines and small circular nodes at grid intersections to imply die/yield data. Cross the wafer with a bold upward-trending analytics arrow from bottom-left to top-right. Extend clean circuit connection lines from both left and right across the midline, ending in rounded endpoints. Use simple geometric shapes only, rounded line caps and joins, and keep the composition symmetrical and visually centered. Color palette: Background gradient from deep red #7F1D1D (bottom) to primary red #DC2626 with an orange accent #F97316; foreground white #FFFFFF, soft red accent #FCA5A5, light rose highlight #FFE4E6. Include a soft subtle shadow for depth while preserving flat appearance. Ensure high contrast and scalability for small sizes (24x24) with a 128x128 viewBox, optimal for dashboard top-left placement. Include SVG-friendly gradients in defs and reusable groups; no text labels.

The image shows a red and orange square icon with an arrow pointing up, set against a white background. The icon is likely related to email marketing, as indicated by the text at the bottom of the image.
