I want to design one Soc development board based the complex of virtex FPGA and architecture ARM processor ,which provides
a platform for implementation new designs.
There are two questions puzzled me .1) what's part do the FPGA device may act ? 2>and ,if the part is decided ,whether the fpga is limited and don't expands other logical functions ?
Since you have already desided about the processor, you can use the FPGA for custom logic or as a custom coprocessor for the processor. Or it can be used to extend the ISA of the processor.
I don't quite clear about some softs functions in this SoC design flow.
Modsim-Xe-5.7 and ISE-6.1 can be suitable for forepart design ,for example coding and simulating .
protel can finish back-end desing, for example layout.
what do these tools that Design Compiler and PrimeTime (synopsys .ltd) conflict with Modsim and ISE ?
