Timing Analysis and Speed Grade Migration<\/h4>\n<p data-path-to-node=\"10\">If you are using the -11 grade to replace a failed -10 part, the silicon is faster, which is generally &#8220;safer&#8221; for setup times (<span class=\"math-inline\" data-math=\"T_{su}\" data-index-in-node=\"128\">$T_{su}$<\/span>). However, in the Virtex-4 architecture, faster silicon can occasionally narrow your hold-time (<span class=\"math-inline\" data-math=\"T_h\" data-index-in-node=\"231\">$T_h$<\/span>) windows on short paths. We recommend a secondary Static Timing Analysis (STA) in ISE to ensure the faster edge rates haven&#8217;t introduced race conditions.<\/p>\n<h4 data-path-to-node=\"11\">2. Thermal Management at 90nm<\/h4>\n<p data-path-to-node=\"12\">The LX160 has a high static leakage profile. When running at -11 speeds with high logic utilization, the junction temperature can climb rapidly.<\/p>\n<ul data-path-to-node=\"13\">\n<li>\n<p data-path-to-node=\"13,0,0\"><b data-path-to-node=\"13,0,0\" data-index-in-node=\"0\">Thermal Resistance:<\/b> The FFG1148 package has a <span class=\"math-inline\" data-math=\"\\theta_{JC}\" data-index-in-node=\"46\">$\\theta_{JC}$<\/span> of approximately <span class=\"math-inline\" data-math=\"0.2\u00b0C\/W\" data-index-in-node=\"75\">$0.2\u00b0C\/W$<\/span>.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,1,0\"><b data-path-to-node=\"13,1,0\" data-index-in-node=\"0\">Heatsinking:<\/b> A high-performance active or passive cooling solution is mandatory for the Industrial range.

The 1.2V <span class=\"math-inline\" data-math=\"V_{CCINT}\" data-index-in-node=\"100\">$V_{CCINT}$<\/span> rail must be heavily decoupled near the BGA center to handle the simultaneous switching noise (SSN) of the 152k logic cells.
