Unlike the 1.0mm pitch found in larger Virtex-4 parts, the SF363 requires tighter PCB design rules. Engineers should ensure their fabrication house can handle the required via-in-pad or fine-line traces necessary to breakout the inner rows of the 363-ball grid.<\/p>\n<h4 data-path-to-node=\"11\">2.

However, the smaller 17x17mm package has a higher thermal resistance (<span class=\"math-inline\" data-math=\"\\theta_{JA}\" data-index-in-node=\"139\">$\\theta_{JA}$<\/span>) than the larger FFG668. If your design is hitting high logic utilization at -11 speeds, pay close attention to the thermal dissipation path through the PCB ground planes.<\/p>\n<h4 data-path-to-node=\"13\">3. Timing Slack &amp; Migration<\/h4>\n<p data-path-to-node=\"14\">The -11 speed grade is often specified to resolve setup time (<span class=\"math-inline\" data-math=\"T_{su}\" data-index-in-node=\"62\">$T_{su}$<\/span>) bottlenecks in high-speed memory interfaces or custom LVDS backplanes. When replacing an older -10 grade part with this -11 variant, verify that your hold time (<span class=\"math-inline\" data-math=\"T_h\" data-index-in-node=\"231\">$T_h$<\/span>) margins remain valid in your ISE timing reports.<\/p>\n<p data-path-to-node=\"15\"><span style=\"color: #003366;\"><strong>Legacy Tooling &amp; Software Support<\/strong><\/span><\/p>\n<p data-path-to-node=\"16\">As with the entire Virtex-4 series, the XC4VLX25-11SFG363I is supported by <b data-path-to-node=\"16\" data-index-in-node=\"75\">Xilinx ISE Design Suite (14.7)<\/b>.
