Yesterday, 21:12KlausST replied to a thread How to find the operating frequency for an ASIC? in ASIC Design Methodologies and Tools (Digital)Hi, The usual way is to set the timing constraint first, then the compiler should optimize it to match the specifications. If you first set to...2 replies | 85 view(s) -
Yesterday, 10:48Hi, Rather straight forward: If cos = 0, then there are just two possible solutions: Phi = 90° when sin = positive Phi = 270° when sin =...13 replies | 242 view(s)
