Added new divisible 36x36 multiplier cell library for architectures which has fracturable dsp36:
- The 36x36 multiplier is form from sixteen 9x9 multipliers.
- It operates same modes with existing library. It can operate in 3 fracturable modes:
1. one 36-bit multiplier
2. two 18-bit multipliers
3. four 9-bit multipliers
- It provides ~%20 better area than existing cell library (mult_36x36.v)
Comparison made with Synopsys Design Compiler NXT:
mult_36x36.v Total cell area 20470 um2
frac_mult_36x36.v Total cell area 15103 um2
