A critical factor is signal rise time; for instance, a transistor-transistor logic (TTL) signal with a 600-ps rise time is considered high-speed.

Trace spacing should adhere to the \u200b\u200b&#8221;3W&#8221; rule\u200b (edge-to-edge separation of at least three times the trace width) to prevent crosstalk. Simulations confirm that maintaining this spacing suppresses crosstalk to microvolt levels.<\/li>\n\n\n\n<li>\u200b<strong>Minimizing Discontinuities:\u200b<\/strong>\u200b\n<ul class=\"wp-block-list\">\n<li>\u200b<strong>Vias:\u200b<\/strong>\u200b Avoid vias wherever possible. When essential, ensure symmetrical via configuration for differential pairs to convert discontinuity into common-mode noise. A via on a 93-mil thick board introduces approximately \u200b0.7 pF of capacitive discontinuity; this impact is more severe on thicker boards.<\/li>\n\n\n\n<li>\u200b<strong>Bends:\u200b<\/strong>\u200b Avoid 90-degree right-angle bends.

At layer change points, abundant ground vias must be provided adjacent to signal vias to ensure return currents have a low-inductance path.

A fundamental rule is to place power and ground planes as close together as possible.

It offers \u200bhigh energy efficiency\u200b and \u200bextremely low latency\u200b because the algorithm is implemented in dedicated hardware circuits.<\/li>\n\n\n\n<li>\u200b<strong>GPU (Graphics Processing Unit):\u200b<\/strong>\u200b A GPU is a mass-produced, highly parallel processor optimized for processing large blocks of similar data (e.g., graphics pixels, AI model calculations). It excels at \u200bhigh computational throughput\u200b for parallelizable tasks.<\/li>\n<\/ul>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">5. \u200bIs A FPGA better than a GPU?<\/mark><\/strong><\/p>\n\n\n\n<p>One is not universally &#8220;better&#8221; than the other.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use an \u200b<strong>FPGA<\/strong>\u200b when you need to create custom, efficient hardware for a specific, non-standard task, or when low latency is critical.<\/li>\n\n\n\n<li>Use a \u200b<strong>GPU<\/strong>\u200b for massive, highly parallel computational workloads like AI training or graphic rendering.<\/li>\n\n\n\n<li>They often work together in systems, with the FPGA handling specialized data preprocessing before sending it to the GPU.<\/li>\n<\/ul>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">6.
