During this phase, designers <strong>determine the positions of major functional blocks<\/strong>, <strong>define power distribution networks<\/strong>, and <strong>allocate space for interconnect routing<\/strong>.<\/p>\n\n\n\n<p>Key activities in floorplanning include:<\/p>\n\n\n\n<ul>\n<li>Defining core area and die dimensions<\/li>\n\n\n\n<li>Placing I\/O pads around chip perimeter<\/li>\n\n\n\n<li>Allocating space for power and ground rings<\/li>\n\n\n\n<li>Positioning hard macros (RAMs, ROMs, analog blocks)<\/li>\n\n\n\n<li>Creating initial wire planning estimates<\/li>\n<\/ul>\n\n\n\n<p>Modern floorplanning tools use sophisticated algorithms to optimize block placement based on connectivity patterns, helping minimize wire lengths and reduce signal delays.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Placement<\/strong><\/h3>\n\n\n\n<p>After floorplanning, the placement stage <strong>positions all standard cells within the defined areas<\/strong>.

(vertical connections between layers)<\/li>\n<\/ul>\n\n\n\n<p>Modern chips use <strong>10-15 metal layers for routing<\/strong>, with each layer having specific
