AR# 2281
M1.5/M1.4/M1.3 MAP: Automatic insertion of GSR/GR is not supported in M1.
Description
Keywords: Map, GSR, GR, STARTUP symbol.
Urgency: Standard
Reference #: 11546 (sh_w)
General Description:
Automatic insertion of GSR/GR is not supported in M1.
Solution
To access the global reset or set/reset resource on the XC4000E/L/EX/XL devices, users must manually instantiate a STARTUP symbol in their design and connect up the GSR pin to an input pin in schematic. Refer to the on-line (Xilinx Manual Libraries Guide).
If you are doing your design in HDL, you must instantiate the STARTUP block and make the same connections to the GSR pin.
