Choosing the implementation platform for TDC—whether to use a flexible Field-Programmable Gate Array (FPGA) or a custom Application-Specific Integrated Circuit (ASIC)—is one of the most critical strategic decisions in product development. This decision is far from being as simple as “FPGA for prototyping, ASIC for mass production”; it involves a complex trade-off across multiple dimensions … Read more
01 Introduction Have you ever wondered how we can accurately measure “time”? You might say, just use a stopwatch, right? But what if we need to measure not in seconds, but in picoseconds (ps) — trillionths of a second? This is not science fiction; in radar, laser ranging, and high-energy physics experiments, precise time measurement … Read more
AliMei Introduction The author encountered C++ exceptions while investigating a bug, and takes this opportunity to clarify the C++ exception mechanism for everyone’s reference. Recently, while investigating a bug, we encountered C++ exceptions. Since we rarely use C++ exceptions, this is a good opportunity to clarify the C++ exception mechanism. There is not much existing … Read more
