Using vsc.randselect or vsc.distselect with a vsc.randobj class?

[stephenmm]

It is not clear to me how I am supposed to integrate vsc.randselect or vsc.distselect with a vsc class (@vsc.randobj class item_c(object):)? I would think it would be called when ci.randomize() is called but the example only shows it being used stand alone.

Is there a simple example showing the preffered/intended use of the *select functions with an actual vsc.randobj?

I thought maybe you use it in the constraint but that does not seem to work for me:

@vsc.randobj
class item_c(object):
    def __init__(self):
        self.a = vsc.rand_uint8_t()
        self.b = vsc.rand_uint8_t()

    @vsc.constraint
    def a_dist_c(self):
        self.a == vsc.distselect([1,1,10,10])  

v3 = []  

ci = iten_c()  

for _ in range(100):
    ci.randomize()
    v3.append(ci.a)  

# v3:
#  3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3 ...

I believe randselect and distselect are meant as analogues to randcase in SV, which you would use to randomize procedural code. There is a distribution constraint you can use within a constraint block/function here: https://fvutils.github.io/pyvsc/constraints.html#dist
