Apart from the suite of tests included in CASCADA, we have tested the search for low-weight characteristics in the primitives listed above by revisiting the following work listing the weights of optimal characteristics covering small number of rounds:

XOR differential and linear characteristics of AES [Mou+11, Table4]

XOR differential and linear characteristics of CHAM, [Roh+19, Table 10, Table11]

linear characteristics of Chaskey [LWR16, Table 4]

XOR differential and linear characteristics of HIGHT [Yin+17, Table 4, Table 7],

XOR [KLT15, Table1], related-key XOR [Wan+18, Table 5] and RX [Lu+20, Table 5] differential characteristics of Simeck,

XOR [LLW17, Table 1] related-key XOR [Wan+18, Table 5] and RX [Lu+20, Table 5] differential characteristics of Simon,

XOR differential and linear characteristics of SKINNY [Bei+16, Table 7]
