Hi,
   I am new to FPGA design, and have been searching through the Xilinx webpages.  I want to use a Spartan 3A with IP including  a CPU (the MicroBlaze?), an embedded ethernet web server, some ram (xxKB TBD, preferably internal), some non-volatile memory (xxKB TBD, either internal or external), some GPIO's, a USB interface, an IIC interface and an SPI interface.  I'd also like to use a real time clock if possible.  It is NOT a high speed design.
   I cannot figure out which Design Tools are needed for this combination.  Can I use the free ISE WebPACK?  If not, how much will a minimal design suite cost for this? 

Any help would be appreciated,

Thank you.  So I've attempted to wade through the licensing options, and am basically confused.  What is required to get the EDK?   It looks like the EDK costs $495.  Then do I have to also purchase the ISE Design Suite?
  It appears when I get the starter kit, I get the WebPACK software and ISE Foundation software.  Do I have to purchase the EDK separately?  Would I need to purchase the SDK also?
   I'm just trying to determine what I would need to purchase and how much it would cost.
