3.2.8. Entering Pin Assignments in HDL Code
You can use synthesis attributes or low‑level I/O primitives to embed I/O pin assignments directly in your HDL code. When you analyze and synthesize the HDL code, the information is converted into the appropriate I/O pin assignments. You can use either of the following methods to specify pin‑related assignments with HDL code:
- Assigning synthesis attributes for signal names that are top‑level pins
- Using low‑level I/O primitives, such as ALT_BUF_IN, to specify input, output, and differential buffers, and for setting parameters or attributes
