RAMB36 features =============== This fuzzer emits features that only are used in the RAMB36E1 cell. There are 3 categories: - ECC - RAM extension - Odd address modes Odd address modes ----------------- Most RAMB36E1 address widths are expressed by configuring the underlying RAMB18E1 to handle half of the data. So `RAMB36.READ_WIDTH = 4` is expressed as `RAM18_Y0.READ_WIDTH = 2` and `RAM18_Y1.READ_WIDTH = 2`. However two address widths (1 and 9) are odd (e.g. not divisible by 2). In these cases, a RAMB36E1 specific feature is used. So `RAMB36.READ_WIDTH = 9` is expressed as: - `RAMB18_Y0.READ_WIDTH_4` - `RAMB18_Y1.READ_WIDTH_4` - `RAMB36.BRAM36_READ_WIDTH_1` and `RAMB36.READ_WIDTH = 1` is expressed as: - `RAMB18_Y0.READ_WIDTH_1` - `RAMB18_Y1.READ_WIDTH_1` - `RAMB36.BRAM36_READ_WIDTH_1`
