4.1i CORE Generator - Multiply Generator v4_0: MULT18X18S is not generated, even though CE Overrides is disabled


Keywords: CORE Generator, COREGen, multiplier, MULT18X18S, CE, override, SCLR, 4.1

Urgency: Standard

General Description:
If a multiplier is created with no clock enable and no clear, then the MULT18X18S should be used, given appropriate settings for the other parameters. If ce_overrides is set to CE_Overrides_SCLR (the GUI default), then a MULT18X18 is used instead, even though the multiplier has no CE and no SCLR.


To obtain the desired behavior using the GUI, you must turn on clock enable and SCLR, change the "ce_overrides" to "SCLR_Overrides_CE", then turn off clock enable and SCLR.

This problem should be fixed in next version of Multiply Generator v5_0, which is expected to be released at the end of February, 2002.
