@preusser Just out of curiosity I did another experiment with 224 different SWG configurations (using OOC synth with 200 MHz target clock):

@pytest.mark.parametrize("idt", [DataType["INT2"], DataType["UINT4"]])
@pytest.mark.parametrize("k", [[3, 3], [5, 5]])
@pytest.mark.parametrize("ifm_dim", [[16, 16]])
@pytest.mark.parametrize("ifm_ch", [8, 32])
@pytest.mark.parametrize("stride", [[1, 1], [2, 2]])
@pytest.mark.parametrize("dilation", [[1, 1], [2, 2]])
@pytest.mark.parametrize("simd", [1, 4, 8, 32])
@pytest.mark.parametrize("dw", [0, 1])
@pytest.mark.parametrize("parallel_window", [0])

Respective configurations with min/max Fmax:

[Before MIN] fmax=141.18 MHz
idt=UINT4, k=[5, 5], ifm_dim=[16, 16], ifm_ch=32, stride=[1, 1], dilation=[2, 2], simd=1, dw=0, parallel_window=0,
[Before MAX] fmax=196.89 MHz
idt=UINT4, k=[3, 3], ifm_dim=[16, 16], ifm_ch=8, stride=[1, 1], dilation=[1, 1], simd=8, dw=0, parallel_window=0,
[After MIN] fmax=139.14 MHz
idt=UINT4, k=[5, 5], ifm_dim=[16, 16], ifm_ch=32, stride=[2, 2], dilation=[2, 2], simd=1, dw=1, parallel_window=0,
[After MAX] fmax=198.85 MHz
idt=INT2, k=[3, 3], ifm_dim=[16, 16], ifm_ch=8, stride=[1, 1], dilation=[1, 1], simd=8, dw=1, parallel_window=0,
