Generic/parameter from top to bottom

Hi,

I have several levels of own IPs in the design.

I want the bottom blocks to have different generics.

I know I canät propagate the generics from bottom to top.

But is there a way to change generics to the different bottom blocks via tcl commands for example ?

Please try to set the parameter with generic option of synth_design.

Ex: synth_design -top wave_gen -part xcku035-fbva900-2-e -generic resp_gen_i0.PWWW=5

In the synthesis log, you can see the below content:

Parameter PWWW bound to: 5 - type: integer

Hi,

I have difficulties to get this passed into the design.

The synthesis always complains, the following:

WARNING: [Synth 8-3301] Unused top level parameter/generic Q_START_BIT_g

BTW, I have a Vivado block design.
