Concept & HDL Direct Project Directory Structure
Concept software generates the following files for each schematic:
- <drawing name>/logic.1.1
- <drawing name>/logic_bn.1.1
- <drawing name>/logic_cn.1.1
- <drawing name>/logic_dp.1.1
For designs that use HDL Direct software, Concept software also generates the following files:
- <drawing name>/logic_dp.1.1
- <drawing name>/logic_vd.1.1
- <drawing name>/logic/verilog.v
- <drawing name>/logic/vhdl.vhd
- <drawing name>/logic/hdldirect.dat
- <drawing name>/entity/vhdl.vhd
These files are stored in their own <drawing name> directories. However, hierarchical relationships between files are not reflected in the file directory structure.
The local SCALD directory has an entry for all <drawing name> directories. Cadence software automatically manages drawing storage and retrieval operations through this special directory. The SCALD directory should have the same name as the UNIX project directory, but with the extension .wrk. Figure 1 shows a sample file structure, with project1 as the UNIX project directory, and project1.wrk as the SCALD directory.
When the concept2alt utility converts the schematic into an EDIF netlist file, it processes the design information and all related file subdirectories, then creates the EDIF netlist file in the directory defined by the user. The EDIF netlist file is named <project name>.edf, where <project name> is the name of the top-level design file. Figure 1 shows the Cadence project file structure.
