Create a register file declaration

Add a register count and width to an empty CX document.

These steps apply to Cloud 2.1.2.10 and Windows 2.1.2.3. On Windows, sign in first. Open a project you can edit and start with an empty CX document.

Create and save the declaration

1. In Digital Design Studio, open Flow Navigator → ISA Design → ISA Authoring.

2. Use the CX document selector in the ISA panel to choose an empty, writable CX file. In a project with no CX files, authoring starts with an empty main.cx.

3. Open the ISA panel, then choose Model → Structure → State / Registers.

4. Under Register files, select New register file to open the declaration form.

5. In CX declaration, replace NEW_REGFILE with Gpr, COUNT with 32, and WIDTH with 32. Keep the enclosing braces.

6. Select Apply to CX to put the declaration in the CX source.

7. Select Save ISA source to save the CX document.
