   Foundation IP  (/products/design/design-ip/foundation-ip/)

   The Foundation IP family page, parent of Memory Compilers, Standard Cell,
   Interface IP and Low Power Foundation IP, built like the LVDS and
   Testability family pages. NO NEW COMPONENTS: .pf-def for the definition,
   .pf-cards for the four lines, and the shared .pf-parts / .pf-ptable for the
   line-by-line coverage table.

   Band rhythm is the homepage's: 48 / 64 / 80. Bands alternate white and
   --ps-color-neutral-2-100; --ps-color-neutral-2-000 is reserved for the
   conversion band. No two adjacent bands share a tint.

     §1  banner        white          §6  proof          neutral-2-100
     §2  what it is    neutral-2-100  §7  evaluate       neutral-2-000

   above the white four-lines band. While it is absent the run shifts one
