What is Clock Domain Crossing? ASIC Design Challenges

WebVerification of these Clock Domain Crossing (CDC) designs presents a daunting challenge as the issues are related to transistor level analog effects in the circuits. The traditional RTL functional simulation verification techniques are insufficient to find these analogue issues. WebFor example, a 300 MHz clock at 2 pixels in parallel supports active video resolutions up to 4096x2160 at 60 Hz. All RTL-based blocks that transfer or receive data from a different clock domain include clock domain crossing (CDC) circuits for both, single bit and data bus signal cases. family ent allergy \\u0026 asthma center
