Functions

unsigned int extract_bits(uint32_t x, uint32_t msb, uint32_t lsb)¶

extract bits between MSB and LSB (including)

return x[MSB:LSB];

Return

extracted value (aligned to lsb=0)

Parameters

• x: Value to extract from

• msb: MSB of extraction

• lsb: LSB of extraction

void set_bits(uint32_t *x, uint32_t v, uint32_t msb, uint32_t lsb)¶

Set bits in variable between MSB and LSB (including)

x[MSB:LSB] = v;

Parameters

• x: Pointer to value where to set

• v: Value to set

• msb: MSB of part to set

• lsb: LSB of part to set

uint32_t optimsoc_get_seed(void)¶

Get a random seed for randomization

This function is used to obtain a random seed from the simulation environment for randomization tests. It has no function when executing in hardware.

It is only random when the actual simulation is seeded with a non-static value.

Return

(random) seed
