WildForce Overview

• File Structure

The following is a breif description of the WildForce VHDL file structure. More information about this can be found in the wildforce manual in the lab. The Following shows the basic structure the WildForce system (The files shown in red are those that the user needs to edit to create a basic WildForce design, also the paths given to the files are relative to the base wildforce installation, currently /cad/WILDFORCE ):

• WildForce Host

• wf4host.vhd
• wfhstcfg.vhd (top level configuration)
• In this file contains the configuration of the WildForce system. That is, each of the component gets an architecture mapped to it along with the appropriate generics. You also specify the various system specifications such as clock frequency and initial memory and fifo contents. In this respect it is similar to the 'config.vhd' file in the Splash system.
• path the templates : "/template/vhdl"


• Fifos
• FIFOIF.vhd / fifo.vhd ( pre-compiled )
• Architectures:
• Behavior (std configuration)
• Blank (not used)
• You specify which architecture you will use in the wfhstcfg file


• Memory: Mezzanine Cards
• mez_card.vhd
• Architectures:
• Memroy (std configuration)
• None (not used)
• path the template : "/template/vhdl"
• You specify which architecture you will use in the wfhstcfg file


• Control / Processing Element 0 [CPE0]
• cpe0e.vhd (entity) path = "/vhdl/src/comp"
• cpe0a.vhd (architecture) path = "/template/vhdl"
• CPE0_Interface
• cpe0ife.vhd (entity)
path = "/vhdl/src/comp"
• cpe0ifa.vhd (architecture) path = "/vhdl/src/comp"
• CPE0_Logic_Core
  • cpe0lce.vhd (entity) path = "/vhdl/src/comp"
  • cpe0lca.vhd (architecture) path the template : "/template/vhdl"


• General Processing Elements 1 through 4
• pe(1-4)e.vhd (entity) path = "/vhdl/src/comp"
• pe(1-4)a.vhd (architecture) path = "/template/vhdl"
• PE_Interface
• pe(1-4)ife.vhd (entity) path = "/vhdl/src/comp"
• pe(1-4)ifa.vhd (architecture) path = "/vhdl/src/comp"
• PE_Logic_Core
  • pe(1-4)lce.vhd (entity) path = "/vhdl/src/comp"
  • pe(1-4)lca.vhd (architecture) path = "/template/vhdl"

Thankfully the WildForce people created a nice makefile that will automatically compile in all of the static VHDL files for you. Using the makefile will be discussed in each of the demos.

Setting Up Your Environment

• .cshrc modifications:

There isn't a whole lot to do here. You simply have to add an environment varialbe pointing to the WildForce installation called WF4_BASE. Add the line "setenv WF4_BASE = /cad/WILDFORCE"

• Synopsys setup

Included in the Wildforce installation are basic versions of both the .synopsys_vss.setup and .synopsys_dc.setup files. You integrate these files into your existing setup files, or you could probably just use these files alone with little modification.The path to the example .synopsys_vss.setup file is, relative to the wildforce install: "/template/synopsys/sim/.synopsys_vss.setup" . The path to the other file is "/template/synopsys/syn/.synopsys_dc.setup". Some sample setup files will be included with the demos.
