Notice that the Save Constraints icon is enabled because there are new design constraints. The cell and design properties you modified in Lab #2 have been added to the Vivado tool in-memory design, but are not yet saved to the target constraint file.
- Click the Save Constraints button
.
The physical constraints you defined in Lab #2 are saved to the target constraint file.
- Select the target XDC (in this case, timing.xdc) from the active constraint set in the Sources window
to open the file in the Vivado IDE text
editor.Note: You might need to click the Reload link to update the file if it is already opened in the GUI.
Notice that the seven
set_property
commands you used in Lab #2 are saved to the constraint file. Only design constraints are written to the XDC file, not the object queries or reporting commands that you also used in this lab. - Look for the following constraints in the open constraint
file:
set_property BEL MMCME2_ADV [get_cells clkgen/mmcm_adv_inst] set_property LOC MMCME2_ADV_X1Y0 [get_cells clkgen/mmcm_adv_inst] set_property PROHIBIT true [get_bels IOB_X1Y34/PAD] set_property PROHIBIT true [get_sites AA8] set_property DOA_REG 1 [get_cells \ {fftEngine/fftInst/ingressLoop[7].ingressFifo/buffer_fifo/infer_fifo.block_ram_\ performance.fifo_ram_reg}] set_property DOB_REG 1 [get_cells \ {fftEngine/fftInst/ingressLoop[7].ingressFifo/buffer_fifo/infer_fifo.block_ram_\ performance.fifo_ram_reg}] set_property CONFIG_MODE M_SERIAL [current_design]
- Exit the Vivado IDE.
