Hi, Running a Protel schematic through the rules checker before going anywhere near the PCB layout (or SPICE for that matter) is a very good idea. Protel may do this automatically when you create a netlist, but check all the option settings to make sure it does what you want. Rule checking can o

Anand, you are asking questions to which the answers shall be as varied as the number of respondents. The answers will of course be based upon the environments where the designers work. Some designers are actually EEs and they do all the design including PCBs, some are EEs but only do the

Yes, you trust the schematic and its netlist. If it is wrong, then the person that did the schematic screwed up. Now of course you can tell them you spotted something, like a power pin that was floating because they were using hidden pins and forgot to connect the right name, but don't fix it for

I'm using Altera FPGAs exclusively, since the tools are an effort in itself. I also find the handling of MaxPlus2 rather awful, Quartus2 is a bit better. The functionality they provide is far beyond just a schematic editor. They allow me have graphic modules ( forget the VHDL for now) to make a hi

One reason to get the drawing in Protel and then export it to the Xilinx tools is that the schematic editor of Xilinx is not, how shall I put it, particularly convenient. I myself have done some designs in it while the rest of the board was done in Protel. This got me out of my hum on more tha

I recently had a look into the subject of FPGA and Protel. I was told the FPGA router is still taken from the manufacturer (in your case XILINX). Meaning you're just using Protel to draw the schematics and send the netlist to the other tool doing the FPGA. These tools from various manufacturers a
