Hi all, I am asked to design a new PLL. I have read some papers and decided to do as follows:
1. Build the block of the PLL using Matlab or VerilogA . I donnot know these 2 tools well. Someone said Matlab is more quickly and intuitionistic, but it cannot include noise effect. Nevertheless I still tend to use matlab,for I can use matlab in other project after I study matlab. Later on, someone tell me that matlab can do noise simulation, the question lies in that the correct noise model. Who is wrong?Please recommend to me which tool is better and give me your comment, thank in advance. In either 2 tools , how can I insert the correct noise model to get the system response?
2. Once I got the parameters of each block, I can design the schematic in detail. I think this step may be easy compared to the 1st step.

Am I right? Please help me to the right way,Thanks!
