83 | 4. RESOLVED ISSUES |
---|
84 | |
---|
85 | The following issues are resolved in Block Memory Generator v6.2: |
---|
86 | |
---|
87 | 1. Core errors in NGDBuild when the depth is too large (especially for Spartan-6 devices) |
---|
88 | Version Fixed: v6.2 |
---|
89 | - CR 587481 |
---|
90 | - AR 39718 |
---|
91 | |
---|
92 | 5. KNOWN ISSUES |
---|
93 | |
---|
94 | The following are known issues for v6.2 of this core at time of release: |
---|
95 | |
---|
96 | 1. Virtex-6 and Spartan-6: BRAM Memory collision error, when the user selects TDP (write_mode= Read First) |
---|
97 | Work around: The user must review the possible scenarios that causes the collission and revise |
---|
98 | their design to avoid those situations. |
---|
99 | - CR588505 |
---|
100 | |
---|
101 | Note: Refer to UG383, 'Conflict Avoidance' section when using TDP Memory - with |
---|
102 | Write Mode = Read First in conjunction with asynchronous clocking |
---|
103 | |
---|
104 | 2. Power estimation figures in the datasheet are preliminary for Virtex-5 and Spartan-3. |
---|
105 | |
---|
106 | 3. Core does not generate for large memories. Depending on the |
---|
107 | machine the ISE CORE Generator software runs on, the maximum size of the memory that |
---|
108 | can be generated will vary. For example, a Dual Pentium-4 server |
---|
109 | with 2 GB RAM can generate a memory core of size 1.8 MBits or 230 KBytes |
---|
110 | - CR 415768 |
---|
111 | - AR 24034 |
---|
