tabgen
Creates a k-rate array containing an arithmetic sequence at initialization.
This opcode is deprecated. Use genarray in new code. The old name remains available for compatibility.
Syntax
Initialization
istart is the first value. istep is the increment and defaults to 1. It must be nonzero and point toward iend. The array includes iend when the sequence reaches it exactly. For example, 0 through 5 with a step of 2 produces 0, 2, 4.
The opcode allocates a one-dimensional k-rate output array and fills it during initialization. It does not refill the array on each control cycle.
Replacement
Change kArray = tabgen(istart, iend, istep) to kArray = genarray(istart, iend, istep), keeping the bounds and step at i-rate. The form with i-rate bounds preserves initialization-only generation into a k-rate array.
Use genarrayi when you want to make that timing explicit. Passing k-rate bounds to genarray instead selects performance-time generation. See genarray for both rates.
See genarray for examples and the supported forms.
