Answers Database COREGEN, 4K: Estimating the number of 4K RAM/ROM primitives used in COREGen memories / When does COREGEN use 16x1 and 32x1 RAM/ROM primitives Record #5165 Product Family: Software Product Line: Coregen Product Part: Coregen Problem Title: COREGEN, 4K: Estimating the number of 4K RAM/ROM primitives used in COREGen memories / When does COREGEN use 16x1 and 32x1 RAM/ROM primitives Problem Description: Urgency: Standard General Description: How to estimate the number and type of RAM and ROM primitives used inside a COREGen RAM or ROM. Solution 1: SINGLE PORT RAM: -------------------------------------------------------- RAM/ROM depth RAM/ROM primitive(s) used -------------------------------------------------------- 16 single 16x1 32 single 32x1 48 One 16x1 + One 32x1 >48 16x1's only DUAL PORT RAM: Only 16x1 primitives are used -------------- See (Xilinx Solution 4710) for information on implementation rules in LogiBLOX) End of Record #5165 - Last Modified: 12/14/98 18:32
